The surface area of a sphere can be found using the formula SA=4(x)pi(x)R squared. Middleton Middle School wants to paint kickballs purple for their carnival. The kickballs are all the same size. They used 6923.7 inches of paint when painting 5 kickballs. What is the radius of each purple kickball? Use 3.14 for pi
x=times

10.5 inches

Step-by-step explanation:

SA = 4 pi r^2

Since there are 5 balls, multiply by 5

6923.7 = 5 *  4 pi r^2

6923.7 = 20 * 3.14 r^2

6923.7 = 62.8 r^2

Divide each side by 62.8

6923.7/62.8 = 62.8/62.8 r^2

110.25 = r^2

Take the square root of each side

sqrt(110.25) =sqrt( r^2)

10.5 = r

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
