Question

find the surface area of a sphere with diameter 30 m. leave your answer in terms of pi. a. 900 pi square meters b. 3,600 pi square meters c. 4,500 pi square meters d. 36,000 pi square meters

Answer 1

`900 \pi` square meters

Explanation:

Given:

diameter
`d=30m`

radius
`r=(d)/(2)=15m`

using the formula for surface area of sphere, we get:

`area_s=4* \pi * r^2`

`=4*\pi * 15^2\\\\=900* \pi m^2`
