Question

Taking = 3.14, find the circumference of a circle whose radius is 15 cm.

Answer 1

Hi there,

Given,

Radius of the circle = 15 cm

As we know,

Circumference of a Circle = 2$\pi r$

hence,

Circumference will be = 2×3.14×15

= 94.2 cm

Thank you

Answer 2

Solution :

Radius of the circle ( r ) = 15cm

π = 3.14

Circumference of the

Circle ( C ) = 2πr

= 2 × 3.14 × 15 cm

= 30 × 3.14

= 94.2 cm

Therefore ,

Circumference of the circle

= 94.2 cm
