Question

Find the circumference of a circle with radius, r = 16m. Give your answer in terms of π .

Answer 1

We have,

Radius of the circle = 16 m

We know,

Circumference = 2πr

∴ Circumference = 2π × 16 m = (32π) m.

Answer 2

`32\pi` meters

Explanation:

The formula for finding the circumference of a circle is
`C=2\pi r`, where
`C` = circumference and
`r` = radius. In this case, we are solving for
`C` and we know that
`r=16`, so after substituting
`r=16` into
`C=2\pi r`, we get:

`C=2\pi r`

`C=2\pi *16` (Substitute
`r=16` into
`C=2\pi r`)

`C=32\pi` (Simplify RHS)

Hope this helps!
