Question

a sphere has a surface area of 9244 square feet what is the radius of the sphere use 3.14 for pi and round to the nearest hundredth

Answer 1

By definition, the surface area of the sphere is given by:
A = 4 * pi * r ^ 2
Where,
r: sphere radio
Clearing r we have:
r ^ 2 = A / (4 * pi)
r = root (A / (4 * pi))
Substituting values we have:
r = root (9244 / (4 * 3.14))
r = 27.12908515
round to the hundredth:
r = 27.13 feet
Answer:
The radius of the sphere is:
r = 27.13 feet
