Given
a circle with diameter 8 yd
Find
the circumference in feet and yards
Solution
The circumference of a circle is given by ...
C = πd
where C is the circumference and d is the diameter. For your circle, the circumference is
... C = π(8 yd) = 8π yd ≈ 25.13 yd
There are 3 feet in a yard, so 3 times as many feet.
... C = 24π ft ≈ 75.40 ft
