Question

The circumference of a circle is 8.34cm. Find the length of the diameter. Give your answer rounded to 2 DP.

Answer 1

Diameter, D = 2.65 cm

Explanation:

Given the following data;

Circumference of circle = 8.34 cm

To find the length of its diameter;

Mathematically, circumference of a circle is equal to;

C = πD

Where;

• C is the circumference of a circle.
• D is the diameter of a circle.
• Pie, π = 3.142

Substituting into the formula, we have;

8.34 = 3.142 * D

`D = \frac {8.34}{3.142}`

Diameter, D = 2.65 cm
