Question

The circumference of a circle is 25.12 millimeters. What is the circle's diameter

Answer 1

8

Explanation:

C = πd

25.12 = 3.14 x d

25.12/3.14 = 3.14d/3.14

8 = d

Answer 2

8 mm

Explanation:

Circumference is pi multiplied by diameter

therefore we can set up the equation

πd=25.12

we can call π 3.14

so then

3.14d=25.12

divide both sides by 3.14

d=8
