Question

The area of a round table in Kim’s living room is 201 square inches. What is the circumference of the round table, to the nearest hundredth of an inch? A.100.49 inchesC.50.24 inchesB.89.03 inchesD.25.12 inches

Answer 1

C. 50.24 inches

Explanation:

The area of a circle can be represented by
`\pi r^(2)`. To find the circumference, all we need to do is know the radius, and then we can plug that value into the circumference formula
`2\pi r`. So, to find the radius we see that:

`\pi r^(2) = 201`

`r = \sqrt{(201)/(\pi ) }`

So, the circumference is:

`2\pi (\sqrt{(201)/(\pi ) })`, which is closest to the answer C) 50.24 inches.

Hope this helped! :)
