Question

Area and perimeter of a circle with a 13 ft radius

Answer 1

Explanation:

area of a circle = πr²

perimeter of a circle = 2πr

all we have to do is substitute the value into the formula:

area of this circle = 22/7 × 13² = 531.14 ..

perimeter of this circle = 2 × 22/7 × 13 = 81.71 ..

hope this helps!
