Question

Find the circumference of a circle with diameter,

d
= 24cm.
Give your answer in terms of
π
.

Answer 1

Explanation:

The circumference of the circle is
`2\pi r` or
`\pi d`

Where r is the radius and d is the diameter. The diameter is 24cm and the radius being half the length of the diameter is 12cm.

So the circumference = 2*
`\pi`*r =
`\pi`*24 = 24
`\pi`
