Question

The radius of a circle is 7m. Find the circumference to the nearest tenth(urgent)

Answer 1

Answer is 44 m

Answer is rounded to the nearest tenth place.

Explanation:

`given \: that \\ radius \: of \: circle \: (r) = 7 \: m \\ we \: know \: that \\ circumference \: = 2\pi \: r \\ on \: substituting \: r = 7 \: m \: in \: formula \\ we \: get \\ circumference \: = 2\pi * 7 \\ = 14\pi \\ substitute \: \pi = (22)/(7) \\ = 14 * (22)/(7) \\ = 2 * 22 \\ = 44 \: m \\ answer \: is \: rounded \: to \: nearest \: tenth.`

HAVE A NICE DAY!

Answer 2

The circumference of the circle is 43.96m. This number rounded to the nearest tenth would make the circumference 44m.

Explanation:

First, we must know the formula for finding the circumference of a circle.

`Circumference = d\pi`

We are given the radius. In order to find the diameter, then we have to multiply the radius by 2 because the radius is half the size of the diameter.

7 * 2 = 14

Now, let's plug in 14 into our formula. We will 3.14 for pi.

`Circumference=(14)\pi`

`Circumference=43.96`

This number rounded to the nearest tenth is 44.
