Question

The area of a circle is approximately 379.94 square inches. What is the diameter of the circle? [Use 3.14 as an approximation for pi.] a0 inches

Answer 1

22

Explanation:

Answer 2

Diameter=22 inches

Explanation:

It is given that The area of a circle is approximately 379.94 square inches, then using the formula for the area of the circle, we get

`A={\pi}r^2`

Substituting the given values, we have

`379.94={\pi}r^2`

⇒
`379.94=3.14r^2`

⇒
`(379.94)/(3.14)=r^2`

⇒
`r^2=121`

⇒
`r=11`

Now, the diameter of the circle is given as:

`D=2r`

Putting the value of r, we have

`D=2(11)`

⇒
`D=22 inches`

Thus, the diameter of the circle is 22 inches.
