Respuesta :

You just need to plug the radii into the formula for the area of a circle, which is A=pi(r)^2.

The radius for the first one is half the diameter. 22 / 2 = 11.

Now plug it into the formula:

A = pi(11)^2
A = 121(pi) square mm. (Don’t forget your units!)

Same thing applies to the second question.
