Question

radius equal to 15 cm what is the circumference of the circle​

Answer 1

Given:

Radius = 15 cm

To Find:

Circumference of the circle

Let's start.

We know that the formula of Circumference is

$\sf \longmapsto2\pi r$

• Put the values
• We know that the formula of $\sf\pi$ is 3.14
• Radius given is 15 centimetre

$\sf \longmapsto \: 2 \times 3.14 \times r$

$\sf \longmapsto2 \times 3.14 \times( 15 \: cm)$

$\sf \longmapsto6.28 \times (15 \: cm)$

$\sf \longmapsto94.2 \: cm$

$\boxed{\red{\boxed{\sf 94.2 \: cm}}}$
