Question

Devon won a tiny bouncy ball at the school carnival. The diameter of the ball is 1.25 inches. To the nearest hundredth of a square inch, what is the surface area of the ball? Use 3.14 for pi.

Answer 1

SA = 4πr^2
SA = 4π)(1.25/2)^2
SA = 4(π)(1.5625/4)
SA = 1.5625π
SA ≈ 4.91

Answer 2

Your awesome! thanks a lot again! Wasn't sure if my procedure was correct!
