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

stira [4]

Answer:

50.24 inches

$\:$

Step-by-step 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 :

$\\{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 2 \times 3.14 \times 8}}}}}} \: \: \\ \\$

${ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 3.14 \times 16}}}}}} \: \: \\ \\$

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

Therefore,

The circumference of the circle is 50.24 inches
