Answer 2

Answer:

Circumference of circle is 94.20 cm

Step-by-step explanation:

As per given information ,

Radius of circle is 15 cm.

We have to find out the circumference of circle.

The circumference means the length of the complete arc of a circle.

As we know that,

Circumference of circle = $2 \times \pi \times r$

Where,

r is a radius of circle.

Put the value of r ,

Circumference of circle = $2 \times \pi \times 15$

Circumference of circle = $30\times \pi$

Put the value of π = 3.14

Circumference of circle = $30 \times 3.14$

Circumference of circle = 94.20

Hence,

Circumference of circle is 94.20 cm
