Weegy: area = 4 · pi · r2 is the formula for the surface area of a sphere. 4 *3.14 * .75^2 = 7.07 inches squared for the surface area of the ball

Devin won a tiny bouncy ball at the school carnival. The diameter of the ball is 1.25 inches.
Surface area = 4*pi*r^2
= 4*3.14*0.625^2
= 12.56*0.390625
= 4.90625
To the nearest hundredth of a square inch, the surface area of the ball is 4.91 square inches.

You are right, my mistake. I had .75 for the radius instead of .625.
