Question

Find the circumference and area of a circle the radius is 7 meters

Answer 1

Answer: 43.9823

Explanation:

The equation to find the circumference is c=2πr. By the “r” in the equation represents the radius. The question says the radius is 7 so you just input the 7 where the “r” is. So 2·π·7=43.9823.

C=2πr=2·π·7≈43.9823
