Question

Circle P has a circumfrence of aproximately 75 inches what is the aproximate length of the radius, r? Use 3.14 for pi. Round to the nearest inch​

Answer 1

The approximate length of the radius, r is 12 inch.

Explanation:

Given:

A circle P is given having circumference C,

C = 75 inch

pi = π = 3.14

radius = r

To Find:

radius = r = ?

Solution:

Circumference:

In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.

That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.

Formula is given as

`Circumference=2\pi (radius)`

Substituting the values we get

75 = 2 × 3.14 × r

∴
`r =(75)/(2* 3.14)\\ \\r=(75)/(6.28) \\\\r=11.942\ inches`

We approximate radius to

radius = 12 inich
