Question

A circle has a circumference of 615.44 units. What is the radius of the circle?

Answer 1

Answer:98

Explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

we have

C=615.44\ units

assume

\pi=3.14

substitute and solve for r

615.44=2(3.14)r

r=615.44/6.28

r=98\ units

Answer 2

The radius of the circle is
`r=98\ units`

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

we have

`C=615.44\ units`

assume

`\pi=3.14`

substitute and solve for r

`615.44=2(3.14)r`

`r=615.44/6.28`

`r=98\ units`
