Question

The circumference of a circle is 94.2 kilometers. What is the circle's diameter?

Answer 1

The diameter would be 29.98 kilometers.

Explanation:

We know that our circumference is pi * diameter, so we just have to divide 94.2 by pi to solve.

Answer 2

30 km

Explanation:

We can use the below formula to find the diameter of a circle.

C = π × d

Here,

C ⇒ circumference ⇒ 94.2 km

d ⇒ diameter

To find the diameter make d as the subject in the above formula.

d = C / π

d = 94.2 / 3.14

d = 30 km
