we can use the formula r=√s/12.6 to relate a balls surface area s( in square centimeters) to its radius r (in centimeters). suppose a ball has a radius of 13.28 centimeters. what is its surface area?

Answer 1

To find the surface area of the ball with a radius of 13.28 centimeters, we can use the formula:

r = √s/12.6

Rearranging the formula to solve for the surface area:

s = (12.6 * r)^2

Plugging in the radius value of 13.28 centimeters:

s = (12.6 * 13.28)^2

Simplifying:

s = (167.328)^2

s = 27999.247744

Therefore, the surface area of the ball is approximately 27999.247744 square centimeters.
