| August 18, 2021 | education
1) What is the radius of the circle?
In order to find the radius of a circle, you need to divide the diameter of the circle in half.
24: 2 = 12 cm.
2) What is the area of the circle?
To find the area of a circle, use the formula S = π * r ^ 2.
S = π * 12 ^ 2 = 144 π cm ^ 2.
3) What is 5/8 the area of a circle?
(5/8) * S = (5/8) * 144 π = (5 * 144 π) / 8 = 720 π / 8 = 90 π cm ^ 2.
Answer: 90 π cm ^ 2.
