The area of circle A is 36 times greater than the area of circle B. If the radius of circle B is 5 meters. What is the radius of circle A?

A. 5 meters

B. 30 meters

C. 32 meters

D. 36 meters

Each number is getting multiplied by pi, but they get squared before that. Let's find what Circle B's radius is when squared.

5²=25

Let's multiply that by 36.

25*36=900

So, the radius of Circle A is the square root of 900.

√900=30

So, the answer is B. 30
