Both circles have the same center. What is the area of the shaded region? r=10 m 7 m Use 3.14 for . Write your answer as a whole number or a decimal rounded to the nearest hundredth. square meters
Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm

Find the area of the circle. Write your solution in terms of and round to the nearest hundredth.
Area in in decimal form: ______
Answer:
A = 25π cm²
In decomal form = 78.5cm²
Step-by-step explanation:
Area of a circle is expressed as;
A = πr²
r is the radius of the circle
Since we are not given the radius. Let us assume that r = 5cm
Substitute into the formula;
A = π(5)²
A = 25π cm²
As a decomal;
A = π(5)²
A = 3.14 * 25
A = 78.5cm²
Note that the radius of the circle was assumed. The same calculation can be employed for any value of the radius
2. An empty ice cream cone has a height of 3.02 inches and a radius
of 0.98 inches. What is the approximate volume of ice cream it will
hold within the cone (not heaped over)?
F. 1 in3
G. 3 in 3
H. 9 in
J. 12 in
Answer:
Approximate volume of ice cream = 3.03 inches
Step-by-step explanation:
Given - An empty ice cream cone has a height of 3.02 inches and a radius
of 0.98 inches.
To find - What is the approximate volume of ice cream it will hold within the cone ?
Proof -
We know that,
Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
where
r is the radius of the cone
h is the height of the cone
Here,
Given that,
r = 0.98 inches
h = 3.02 inches
So,
Volume = [tex]\frac{1}{3}\pi r^{2}h[/tex]
= [tex]\frac{1}{3}(3.14) (0.98)^{2}(3.02)[/tex] ( Consider the value of [tex]\pi[/tex] = 3.14)
= 3.0373
∴ we get
Approximate volume of ice cream = 3.03 inches
So,
The correct option is - G. 3 in 3
Drag and drop the numbers 1 - 9 into the empty
boxes to the right to create a right triangle with the largest area
possible (round to the nearest TENTH, if necessary).
Each number can only be used one time, and only one number
can be placed per empty box (there will be some unused
numbers).
Answer:
9 for the hypotenuse, [tex]\sqrt{64}[/tex] and [tex]\sqrt{25}[/tex] for the two legs
Step-by-step explanation:
For these types of problems, we need to make sure that the values of legs are as big as possible while keeping the hypotenuse larger than legs because otherwise, it won’t be a right triangle.
So for the hypotenuse, we have to put the largest number in this number bank because the hypotenuse has to be larger than both legs. So the hypotenuse will equal 9. The rest is simple. Get the numbers as large as possible. Since the hypotenuse must be larger than both legs, we cannot use sqrt(81) and sqrt(64) (that would’ve been sweet). So we have to use sqrt(64) and sqrt(25) because sqrt(49) and sqrt(36) are already taken since we can only use a number once.
I'm not an expert at this and I cannot guarentee that this is correct. But I hope that this helps.

Two cards are drawn from a deck of 52 cards. What is the probability that the first card
drawn is a king and the second card drawn is a heart, given that the first card is
replaced? (Hint: A deck has 4 kings and 13 hearts)
Answer:
1) P(First card was a king) = 1/13 2.) 1/4
Step-by-step explanation:
1) P(First card was a king) = n(King)/n(Total) = 4/52 = 1/13
2. P(Heart)13/52 = 1/4
Answer:
1/52
Step by step explanation:
First, find the probability that the first card will be a King. Since there are 4 possible kings, and 52 cards, the probability is 4/52.
Then, find the probability that the second card will be a heart. "given that the first card is replaced" means that there are 13 possible hearts regardless of the suit of the first card. So 13/52 is the probability.
To find the probability of both occurrences, multiply them.
4/52 * 13/52 = 52/2704
52/2704 can be simplified to 1/52. So that is the probability that the first card will be a king and the second card will be a heart.

Step-by-step explanation:
if the marginal revenue is higher than marginal cost the monopoly can increase profit by
Answer:
If the marginal revenue exceeds the marginal cost, then the firm can increase profit by producing one more unit of output. For example, at an output of 4 in Figure 3, marginal revenue is 600 and marginal cost is 250, so producing this unit will clearly add to overall profits.

Using the properties of a parallelogram, can you determine which are parallelograms? Answer choices are in the picture.
The following figures are parallelograms:
Figure A
Figure B
Figure E
==================================================
Explanation:
If the diagonals of the quadrilateral are the same length (aka congruent), then we can prove that we have the opposite sides parallel. That would conclude in the figure being a parallelogram. Therefore, choice A is a parallelogram because of this fact. Choice C is not a parallelogram because of this.
Also, recall that parallelograms have their opposite sides being the same length. Think of a rectangle, but we can slant the sides as figure B shows. Figure B is a parallelogram due to the opposite sides being the same length. More specifically, it's a rhombus (because all four sides are the same). Any rhombus is a parallelogram, but not the other way around.
One last useful property we'll use is the fact that adjacent angles of a parallelogram are supplementary. This means the angles add to 180. In figure D, the adjacent angles add to 74+105 = 179, which isn't 180. So we rule out choice D. Choice E works though because 55+125 = 180.

18 pi = pi *d
Divide each side by pi
18 pi / pi = pi * d/pi
18 =d
Answer:
18 m
Step-by-step explanation:
C = π · d
18π = π · d
18 = d

Step-by-step explanation:
Jared invests 10000 in a savings account that pays 3% simple interest how many years will it take for the account to grow to 12700 if he makes no withdrawals and deposits
Answer:
9 years
Step-by-step explanation:
Given data
Principal= $10000
Rate= 3%
Final amount= $12700
The simple interest expression is given as
A=P(1+rt)
substitute
12700=10000(1+0.03*t)
12700=10000+300t
collect like terms
12700-10000= 300t
2700=300t
divide both sides by 300
t= 2700/300
t= 9 years

pls answer i’m begging
Answer:
75
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we can find the missing angle by subtracting the measures of the given angles from 180
Thus missing angle = 180 - 34 - 71
180 - 34 - 71 = 75
Which means that the missing angle = 75
Answer:
? = 180 - (angle 1 + angle 2)
? = 180 - (71 + 34)
? = 180 - 105
? = 75°
=> To check is the answer is right, add all 3 angles together and their sum should be 180°
Hope this helps!

Answer:
1) 12 (option b)
2) 41, 9, 40 (option a)
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
1) Let the unknown leg be x cm long. Thus,
5² + x² = 13²
Simplify and solve.
25 + x² = 169
x² = 144
x = 12
2) Apply the Pythagorean Theorem.
9² + 40² = 41² = 81 + 1600 = 1681
1681 = 1681
a is true.
Just in case, let's check the other options.
5² + 8² = 9² = 25 + 64 = 81
89 = 81, false
b is false
10² + 11² = 12² = 100 + 121 = 144
221 = 144, false
c is false
3² + 4² = 6² = 9 + 16 = 36
25 = 36, false
d is false
Thus, a is the answer.

Answer:
Hello! answer: 80
Step-by-step explanation:
What I did was find area of the shape all together without the cut out square and that was 96 because 12 × 8 = 96 then I found the area of the square 4 × 4 = 16 so I just subtract that by 96 and then thats are answer so...
96 - 16 = 80 so 80 is our area HOPE THAT HELPS!
