A sphere has a surface area of 200 square centimeters. Which choice is the best approximation of its diameter? Use 3.14 to approximate pi.

SA = surface area of the sphere

SA = 4*pi*r^2

200 = 4*pi*r^2

200 = 4*3.14*r^2

200 = 12.56*r^2

12.56*r^2 = 200

r^2 = 200/12.56

r^2 = 15.9235668789809

r = sqrt (15.9235668789809)

r = 3.99043442233811

The radius is r = 3.99043442233811

so the diameter is

d = 2*r

d = 2*3.99043442233811

d = 7.98086884467621

Answer: 7.98086884467621

Round this however you need to

Yeah he’s correct I think and hope
