Question

What is the area of the circle if XY = 5.4 mm? 5.4π mm2 7.29π mm2 10.8π mm2 14.58π mm2

Answer 1

Answer: 7.29π mm²

Step-by-step explanation:

First, I am assuming XY is the diameter of the circle :)

The formula for the area of a circle is πr² (r = radius)

So that means we need to divide the diameter by 2 to find the radius

5.4 / 2 = 2.7

Now we simply plug in our numbers!

3.14 · 2.7²

3.14 · 7.29

And that's it!

Hope this helped you :)
