Question

The area of a circle is 73.48 square meters. What is the radius?

Answer 1

`\large\boxed{\text{About}\,4.836\,\,\text{meters}}`

Explanation:

In this question, we're trying to find the radius of the circle.

In this case, we would use the formula:

`r=\sqrt(A)/(\pi)\,\,\text{or}\,\,r=\sqrt(A)/(3.14)`

"A" would represent the area, so you would plug in 73.48 in "A."

Your equation should look like this:

`r=\sqrt(73.48)/(\pi)`

Now, you will solve:

`r=\sqrt(73.48)/(\pi)\\\\\text{Divide the fraction}\\\\r=\sqrt23.3894104367849385445951\\\\\text{Square it by finding the square root}\\\\r= 4.836259963730\\\\\text{Lets make it shorter}\\\\r=4.836`

When you're done solving, you should get 4.836

This means that the radius is about 4.836 meters.

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!

Answer 2

r=4.84m

Explanation:

If the area of a circle is 73.48 square meters, the radius is 4.84m.

Formula: A=πr^2

r = A/π = 73.48/π ≈ 4.83626m
