Question

A rhombus has the same perimeter as the circumference of a circle if each side of the Rhombus measure 33 cm find the radius of the circle​.

Answer 1

Perimeter of rhombus is sum of all side = 4AB

=4×33=132 cm

It is equal to the circumference

$2\pi r = 132 \\ 2 \times \frac{22}{7} \times r = 132 \\ r = \frac{132 \times 7}{22 \times 2}$

$r = 3 \times 7 \\ r = 21 \: cm$

The radius of the circle is 21
