Question

Find the exact circumference of a circle with diameter equal to 8 ft. 8 ft. 16 ft. 64 ft.

Answer 1

Answer:

$8\pi\ ft$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

we have

$D=8\ ft$

substitute

$C=\pi (8)=8\pi\ ft$

Answer 2

Answer: $8\pi\ \text{ft.}$

Step-by-step explanation:

We know that formula to calculate the circumference of a circle is given by :-

$\text{Circumference}=\pi d$, where d is the diameter of the circle.

Given: The diameter of the circle : $d=\ 8\ ft.$

Then , the circumference of a circle is given by :-

$\text{Circumference}=\pi (8)=8\pi\ \text{ft.}$

Hence, the exact circumference of a circle with diameter equal to 8 ft = $8\pi\ \text{ft.}$
