Question

What is the circumference of the circle if r = 3.5 feet? use 22/7 for pi

Answer 1

22 feet

Explanation:

the formula for the circumference of a circle is 2πr where r is the radius of the circle. this can also be written as πd where d is the diameter of the circle (because the diameter is 2×r)

2×3.5=7

(22/7)×7=22
