Answer: Circumference: C = 2πr = 16.3
2(3.14)r = 16.3
r = 16.3/6.28
r = 2.5955414
Area: A = πr2
A = 3.14(2.5955414)2
A = 21.15366242 in2
Rounded to nearest whole number the area is 21 in2
Step-by-step explanation:
* Lets revise some rules of a circle
- The circumference of a circle = 2πr , where r is the radius of it
- The area of the circle = πr²
* Lets solve the problem
∵ A circular plate has circumference 16.3 inches
∵ The circumference = 2πr
∵ π = 3.14
- Lets find the radius of the plate
∵ 16.3 = 2(3.14)r
∴ 16.3 = 6.28r
- Divide both sides by 6.28
∴ r = 16.3/6.28 = 2.5955 ≅ 2.6
∴ The radius of the plate is 2.6 inches
* Lets find the area of the plate
∵ The area = πr²
∵ π = 3.14
∵ 4 = 2.6
∴ The area = 3.14(2.6)² = 21.22 ≅ 21
* The area of the plate is 21 inches
Answer:
Step-by-step explanation:
r is the radius
Circumference = 2πr = 16.3
r = 16.3/(2π) = 8.15/π
Area = πr² = π(8.15/π)² = 8.15²/π ≈ 21.1 sq in

Two hamsters work together and move a pile of sunflower seeds in 7 1 2 minutes. How long would it take each hamster to move the same pile alone if one of the hamsters needs 8 more minutes to do the job than the other?
Answer:
Hamster 1: 12 minutes. hamster 2: 20 minutes
Step-by-step explanation:
The first hamster took 8 minutes while the second hamster tool 20 minutes.
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the time required for the first hamster and y the time for the second hamster.
x = y + 8 (1)
(1/x + 1/y)7.5 = 1
[1/(y + 8) + 1/y ]7.5 = 1
y = 12 minutes
x = 12 + 8 = 20 minutes
The first hamster took 8 minutes while the second hamster tool 20 minutes.

A pizza with a diameter of 8 inches costs $10 and a pizza
with a radius of 5 inches costs $12. Which pizza is the
best buy (square inches per dollar)?
Answer:
8 inch is your best buy
Step-by-step explanation:
8inch diameter =10 dollars
5 inch radius = 12 dollars
so if we get each equal to the diameter it should be 10 inch and that would be 24 dollars vs . 8 in for 10 dollars. So best buy would be 8 inch

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles
you get $0.15. How many cans did you recycle?
Answer:
27
Step-by-step explanation:
x + y = 30
0.05x + 0.15y = 1.80
x = 30 - y
1.5 - 0.05y + 0.15y = 1.80
0.10y = 0.30
y = 3 (bottles)
x = 27 (cans)

Answer:
"interquartile range", abbreviated "IQR", is just the width of the box in the box-and-whisker plot. ... The IQR tells how spread out the "middle" values are; it can also be used to tell when some of the other values are "too far" from the central value.

a coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the coin?
Answer:
You would get tails 75 times, or 75:200
Step-by-step explanation:
5:8 = x:200
multiply 8 by 25 to get 200
multiply 5 by 25 to get x (125)
Probability to get heads is 125 so subtract 200 by 125
200 - 125 = 75

3 to the power of negative 4 answer in fraction
Answer:
Step-by-step explanation:
[tex]3^{(-4)}=\frac{1}{3^4}=\frac{1}{81}[/tex]
3 to the power of-4 is equal to the bit 1/81.
To calculate 3 raised to the power of-4 and express the answer as a bit, we can use the fact that a negative exponent indicates the complementary of the base raised to the positive exponent.
In this case
3⁻⁴= 1/3⁴
Now, let's calculate 34 first
3⁴ = 3 x 3 x 3 x 3 = 81
Now, substitute this value back into the complementary expression
1/ 3⁴= 1/ 81
Thus, 3 to the power of-4 is equal to the bit 1/81.
