Question

Find the surface area of a hemisphere with a radius 10m. Leave your answer in terms of pi
500 pi Meters squared
300 pi Meter squared
200 pi meter squared
400 pi meters squared

Answer 1

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

Plugging in the radius of 10m into the formula, we get:
Surface area = 2π(10)^2
Surface area = 2π(100)
Surface area = 200π

Therefore, the surface area of a hemisphere with a radius of 10m is 200π square meters.

So the correct answer is:
200 pi meter squared
