Question

Find the circumference of a circle with radius, r = 16.5m.
Give your answer in terms of pi.

Answer 1

33π is the answer in terms of pi.

Explanation:

Circumference of circle formula is C=πd.

Plug in the given values. We put 33 into d, because d represents diameter, and diameter is twice the radius(16.5), so we multiply 16.5 by 2. So far we have C=(π)(33).

C=(π)(33)=33π
