Question

If a full revolution of a circle is 18.84 cm what is the diameter of the circle

Answer 1

A revolution of a circle is the length of the circumference.

To find the diameter, divide the circumference by PI.

Diameter = 18.84 / 3.14 = 6

The diameter is 6 cm.

Answer 2

a full revolution of a circle is 18.84 cm

Full revolution is the circumference of the circle

we are given with circumference of the circle 18.84 cm

We need to find the diameter of the circle

Formula for the circumference of the circle is = $\pi * d$

Where d is the diameter of circle

we assume the value of pi as 3.14

the circumference of the circle is = $\pi * d$

18.84 = 3.14 * d

To isolate 'd' we divide both sides by 3.14

$\frac{18.84}{3.14} = d$

d = 6

the diameter of the circle is 6 cm
