Question

What is the circumference of a circle with a radius of eight inches

Answer 1

• 50.24 inches

`\:`

Explanation:

It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.

`\:`

To find the circumference of the circle we must know this formula first :

`\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: Circumference_((circle))= 2 \pi r}}}}}} \: \: \bigstar \\ \\`

Where

• r is the radius of the circle.

• We'll take the value of π as 3.14

Now substituting the values in the formula :

`\\{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_((circle))= 2 * 3.14 * 8}}}}}} \: \: \\ \\`

`{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_((circle))= 3.14 * 16}}}}}} \: \: \\ \\`

`{ \longrightarrow \qquad{ { \pmb{\frak{{ \: Circumference_((circle))= 50.24}}}}}} \: \: \\ \\`

Therefore,

• The circumference of the circle is 50.24 inches

Answer 2

C = 50.24 in

Explanation:

Given that,

→ Radius (r) = 8 in

Formula we use,

→ 2πr

The circumference of the circle will be,

→ 2πr

→ 2 × 3.14 × 8

→ 6.28 × 8

→ [ 50.24 in ]

Hence, the circumference is 50.24 in.
