Question

A circle has a circumference of 28.2628.2628, point, 26 units. What is the diameter of the circle?

Answer 1

Answer:

8.28 units

Step-by-step explanation:

The formula for the circumference of a circle is $C=\pi d$

where

$C$ is the circumference of the circle

$d$ is the diameter of the circle

We know form our problem that the circumference of our circle is 26.28 units, so $C=28.26$. Let's replace that value in our formula and find $d$:

$C=\pi d$

$26=\pi d$

Divide both sides of the equation by $\pi$

$\frac{26}{\pi } =\frac{\pi d }{\pi }$

$\frac{26}{\pi } =d$

$d=\frac{26}{\pi }$

$d=8.28$

The diameter of the circle that has a circumference of 28.26 units is 8.28 units.

Answer 2

Answer:

The diameter of a circle is 9 units

Step-by-step explanation:

A circle has a circumference of 28.26

Let diameter of a circle be d unit.

Formula:

$C=\pi d$

where, C=28.26

$28.26=\pi d$

$d=\dfrac{28.26}{\pi}$

$d=8.995\approx 9$

Hence, The diameter of a circle is 9 units
