Question

A circle has a circumference of 361π. What is the diameter of the circle?

Answer 1

361pi divided by 3.14 = 114.91 which is the diameter

Answer 2

The formula to find circumference of circle is given by

`C = 2\pi r`

Where r is radius of circle and pi =3.14

We are given Circumference here as 361π

Plugging the value in the formula :

`361\pi = 2\pi r`

r=361/2 = 180.5

radius of circle is 180.5.

We know that Diameter is double of radius.

So diameter = 2*180.5 = 361

Answer : diameter of circle is 361.
