Answer 2

$\large\mathtt\pink{Circumference\ of\ a\ circle=53.43cm}$

• Given

Radius of a circle = 8.5 cm

• To find

Circumference of a circle

• Solution

We are given the value of the radius of the circle, and we have to find circumference. By substituting the value of radius in the formula - 2πr we will find circumference of the circle.

Take π = 22/7

$\purple{\bigstar}★ \boxed{\underline{\sf{Circumference~of~circle = 2\pi r}}}$

Circumference of circle=2πr

Substitute the given values,

⟶ 2 × 22/7 × 8.5

⟶ 374/7

⟶ 53.43 cm

Circumference of circle = 53.43 cm
