Question

The radius of a circle is 7 m. Find its circumference in terms of
π
π.

Answer 1

`circumference = 2 * \pi * r`

`circumference = 2 * \pi * 7`

`circumference = 14\pi`

Answer 2

14π

Explanation:

Given:

• Radius of circle = 7 m

To determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.

Substitute the radius in the formula:

`\implies 2\pi (r) = \text{Circumference}`

`\implies 2\pi (7) = \text{Circumference}`

Simplify the circumference:

`\implies 2\pi (7) = \text{Circumference}`

`\implies 14\pi = \text{Circumference}`

Thus, the circumference is 14π.
