Question

The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd

Answer 1

6.3 yards

Explanation:

mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle

we have this as;

C = 2 * pi * r

r is 1 yard

c = 2 * pi * 1 = 2pi yards = 6.3 yards
