Find the surface area of a hemisphere with a radius of 10 m leave your answer in terms of pi

A. 200π m^2
B. 500π m^2
C. 400π m^2
D. 300π m^2

The formula for the surface area of a hemisphere with radius r is 2πr^2.

Plugging in the value for r, we get:
Surface area = 2π(10^2) = 2π(100) = 200π m^2

Therefore, the correct answer is A. 200π m^2.
