What is the surface area of a dome (i. e., a half sphere) with a radius of 10 meters? 100π meters squared 200π meters squared 400π meters squared 40π meters squared

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
