That is the awnser so how it helped

Step-by-step explanation:

Answer 2

Answer:

15.00 inches

Step-by-step explanation:

Recall the formula for the surface area of a sphere and a radius of r

A = 4πr²

In our case, we are given that A = 2826 ft² = 406944 in²

so,

406944 = 4πr²

r² = 406944 / (4π)      (use π=3.142)

r² = 406944 / (4π)  = 32383.57

r = √32383.57 = 179.95 in
