Question

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

Answer 1

Answer: 25.12 ft.

Step-by-step explanation:

Given: The diameter of circle d= 8 ft.

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

$\text{Circumference}=\pi d\\\\\Rightarrow\text{Circumference}=(3.14)(8)\\\\\Rightarrow\text{Circumference}=25.12\ ft.$

Hence, the exact circumference of a circle with diameter equal to 8 ft is 25.12 ft.

Answer 2

The circumference of the circle is the linear length of the circle if the arcs are laid linearly. In this case, the formula that must be followed is C = pi D where C is the circumference and D is the diameter. The circumference then is equal to 8 pi ft
