Question

how do you find the circumference whenever you know the radius but you don't know the diameter. radius = 10in

Answer 1

Circumference is 62.8inches

Step-by-step explanation:

To calcuclate the circumference of a circle when given the radius, we will use the formula given;

`C\text{ = 2}\pi r`

r is the radius

Given

radius = 10inches

Substitute

Circumference = 2(3.14)(10)

Circumference = 2 * 31.4

Circumference = 62.8in

Hence the Circumference is 62.8inches
