Answer:
-83, -85
Step-by-step explanation:
Answer:
First, you have to find out the surface area of the box
=> Sbox = 10 x 5 x 2 + 10 x 8 x 2 + 5 x 8 x 2 = 340
Denote Surface area of the ball as Sball, we have:
Sball + Sbox = 352.56
=> Sball = 352.56 - Sbox = 352.56 - 340 = 12.56
From the formula to calculate Sball, we have:
4 x pi x radius^2 = 12.56
=> radius^2 = 12.56/(4 x pi) = 1 (here, pi = 3.14)
=> radius = 1 in
Hope this helps!
