Find the surface area of a hemisphere with a radius 10m. Leave your answer in terms of pi.
1. 500π m^2
2. 200π m^2
3. 400π m^2
4. 300π m^2
The formula for the surface area of a hemisphere is 2πr^2, where r is the radius of the hemisphere.
Plugging in the given radius of 10m into the formula, we get:
Surface area = 2π(10^2) = 200π m^2
Therefore, the correct answer is option 2: 200π m^2.
