Question

Circumference of a circle is 88 cm. Find the diameter of the circle.

Answer 1

Let the diameter be $dcm$

As we know that

Circumference of circle with diameter $d$ is $\pi d$

Given Circumference of a circle is $88cm$

$⟹\pi d=88$

$⟹\frac{22}{7}\times d=88$

$⟹d=\frac{88\times 7}{22}=28$

So the diameter is $28cm$
