Answer:
Figure 1's area is 530.66 centimeters and figure two's is 1589.6250 centimeters
Hey there!
The answers are 706.5 and 1589.625
The formula for the area of a circle is [tex]\pi[/tex][tex]r^2[/tex].
For the first circle, the radius is 15, so let's solve:
[tex]\pi (15^2)[/tex]
[tex]\pi(225)\\3.14(225)\\\\706.5[/tex]
The second circle has a diameter of 45, and the radius is half the diameter, so 45/2 = 22.5. Let's solve:
[tex]\pi (22.5^2)\\\pi (506.25)\\3.14(506.25)\\1589.625[/tex]
Have a super awesome day!

The radius of the other similar circle is, 6 inches
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Angle = Arc / Radius
Given that,
The two arc lengths for the circles are equal
One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees
The second circle has a shaded sector with an angle measure of 120 degrees
The radius of second circle = ?
α = 90°
It is known that,
π radian = 180°
1° = π/180 radian
Now,
α = 90 × π/180
= π/2
β = 120°
= 120 × π/180
= 2π/3
In Circle 1,
Angle = Arc / Radius
π/2 = Arc/8
Arc = 4π
In both the circles, length of arc is same,
In Circle 2,
Angle = Arc / Radius
2π/3 = 4π/Radius
Radius = 6
Thus, the radius of second circle is 6 inches

A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answers
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules

Can the sides of a triangle have lengths 3, 16, and 19?
Answers
The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
Answer:
No
Step-by-step explanation:
Because you have to add the smallest ones which are 3 and 16 if u add them up it = 19 and you cant have 19 , 19 you have to have the smallest numbers ADD UP Greater Than the biggest number, when its equal to itself it doesn't form a triangle because the lengths are short by 1 please tell me if u need more help

The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025

The measure of ⏜ is 161°, and the measure of ⏜ is 107°.
What is the measure of ∠ ?
Answers
Answer:
m<AEB = 46°
Step-by-step explanation:
Given:
Arc AD = 161°
Arc BC = 107°
Required:
m<AEB
Solution:
Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)
This:
m<AED = ½(AD + BC)
m<AED = ½(161 + 107) => Substitution
m<AED = ½(268) = 134°
✔️m<AEB = 180° - m<AED => Linear pair theorem
m<AEB = 180° - 134° => substitution
m<AEB = 46°

Problem 1:
The height of water in a bathtub, w, is a function of time, t. Let P represent this function. Height
is measured in inches and time in minutes.
Match each statement in function notation with a description.
A: P (0)=0
1: After 20 minutes, the bathtub is empty.
B:P (4)= 10
2: The bathtub starts out with no water.
C:P (10) = 4
3: After 10 minutes, the height of the water is 4 inches.
D: P (20) = 0
4: The height of the water is 10 inches after 4 minutes.
Answers
Answer:
A = 2
D = 1
B = 4
C = 3
Step-by-step explanation:
Height of water in bathtub is a function of water in bathtub.
P(t) = w ; t = time ; w = height of water.
A: P (0)=0 ; At time, t = 0 ; height of water = 0, there is no water on bathtub
2: The bathtub starts out with no water.
D: P (20) = 0 ; At time, t = 20 ; w = 0 ;the tub is empty.
1: After 20 minutes, the bathtub is empty.
B:P (4)= 10 `; At t = 4, w = 10 ; height of water in bath tub is 10
4: The height of the water is 10 inches after 4 minutes
C:P (10) = 4 ; At t = 10, w =4, height of water in bathtub = 4 inches
3: After 10 minutes, the height of the water is 4 inches.

Answers
Answer:
x = 31 and y= 11
Step-by-step explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11
