Question

The circumference of a circle is 18.41 feet. WHat is the approximate length of the radius.

Answer 1

The approximate length of the radius is 3 feet

Explanation:

Given:

circumference of a circle = 18.41 feet

To Find:

approximate length of the radius = ?

Solution:

Let the radius of the circle be r

We know that the circumference of the circle C is given by the formula

C =
`2 \pi R`

Substituting the values, we get

18.41 =
`2* \pi * R`

Rearraning the above equation we get

R=
`(14.41)/( 2* \pi)`

R=
`(18.41)/(6.28)`

R= 2.93

R= 3 (approx)

Answer 2

The answer can be calculated by doing the following steps;
