Why is the surface area of a hemisphere with a radius of 10m with the answer in terms of pi 300π m^2 and not 200π m^2

1 answer

The surface area of a hemisphere is given by the formula:

Surface Area = 2πr^2

where r is the radius of the hemisphere.

In this case, the radius is given as 10m.

So, using the formula:

Surface Area = 2π(10)^2 = 200π m^2

Therefore, the correct answer is 200π m^2, not 300π m^2.
