Question

The circumference of a circle is 20 4/35 cm. What is the approximate diameter of the circle? Use 22/7 for π. Enter your answer as a mixed number in simplest form in the box. cm

Answer 1

The approximate diameter of this circle is equal to 6.4 cm.

Given the following data:

• Circumference of a circle = $20\frac{4}{35}$ cm.

• $\pi = \frac{22}{7}$

To determine the approximate diameter of this circle:

How to calculate the circumference of a circle.

Mathematically, the circumference of a circle is given by the formula:

$Circumference = \pi D$

Where:

• D is the diameter of a circle.

Substituting the given parameters into the formula, we have;

$20\frac{4}{35}=\frac{22}{7} D\\\\\frac{704}{35} =\frac{22D}{7} \\\\704\times 7=22D \times 35\\\\4928=770D\\\\D=\frac{4928}{770}$

D = 6.4 cm.
