Question

A 45° sector in a circle has an area of 13.75π cm².

What is the area of the circle?

Use 3.14 for pi.

Enter your answer as a decimal in the box.

Answer 1

As the circle is divided into sectors, first we need to find out how many sectors are in the circle, considering one sector = 45°:

Number of sectors in a circle = 360°/45° = 8

Now multiply this number to 13.75$\pi$ to get the area of the circle.

$\pi$ = 3.14

Area of the circle = 8 * 13.75 * 3.14 = 345.4 $c m^{3}$

Ans: 345.4 $c m^{3}$
