Question

What is the surface area of a sphere with a radius of 30 m?

900π m^2
90,000π m^2
1,800π m^2
3,600π m^2

Answer 1

D: 3,600π m^2

Explanation:

Answer 2

The surface of a sphere is given by the formula:
area=4πr²

Data:
r=30 m

area=4ππ(30 m)²=3600π m².

Answer: the area of this sphere is 3600π m².
