Find the surface area of a hemisphere with a radius 10m. Leave your answer in terms of pi.
400 m²
500 m²
200π m²
300 m²
The formula for the surface area of a hemisphere is given by:
Surface Area = 2πr^2
where r is the radius of the hemisphere.
Plugging in the given value of the radius (r = 10m) into the formula, we have:
Surface Area = 2π(10^2)
= 2π(100)
= 200π
Therefore, the surface area of the hemisphere is 200π m². Thus, the correct answer is 200π m².
