Question

Find the area of a circle having a circumference of 23π units. Round to the nearest tenth.

Answer 1

B. 415.5 units2

Explanation:

Answer 2

`\displaystyle 415,5\:units^2 ≈ A`

Step-by-step explanation:

In the circumference, 27 represents the diameter, and the radius is half the diameter, so take half of it to get 11,5. Then use it in the area formula:

`\displaystyle πr^2 \\ \\ π11,5^2 = 132,25π ≈ 415,4756284 ≈ 415,5`
