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!

Answer:
166 packs
Step-by-step explanation:
Data obtained from the question include:
Total pack of paper needed by Bret 450 packs
Bret currently has = 284 packs
The remaining packs of paper needed by Bret = 450 — 284 = 166 packs
Answer:
64 Divided by 8
Step-by-step explanation:
5x + 4y = 20
4y = 20 - 5x
y = 20/4 - 5/4x
y = 5 - 5/4x
The x intercept is when y = 0
0 = 5 - 5/4x
5/4x = 5
x = 4.5/5
x = 4
The y intercept is when x = 0
y = 5 - 5/4x
y = 5 - 5/4.0
y = 5
