Question

A rhombus has the same perimeter as the circumference of the circle. If the side of the rhombus is 2.2m, find the radius of the circle.

Answer 1

Given the side of a rhombus = 2.2 m

We know that the perimeter of the rhombus = 4 $\times$ side

= 4 $\times$ 2.2 m

= 8.8 m.

Perimeter of the rhombus = Circumference of the circle

8.8 = 2 $\pi r$

$8.8=2\times \frac{22}{7}\times r$

r = 1.4 m

Therefore radius of the circle = 1.4m
