Question

Can someone help me please

Answer 1

Since XY = 5.4, we divide between 2, like this:

5.4/2 = 2.7.

Then, we square the number, like this:

2.7 * 2.7 = 7.29.

And that means the answer would be: 7.29π.

Hope this helped! c:

Answer 3

Here is the formula for finding the area of a circle:

π
`r^(2)` (pi times the radius to the second power)

To find the radius you take 1/2 of the diameter, 5.4÷2=2.7

Then you square root 2.7,
`2.7^(2)`=7.29π m
`m^(2)`

So, your answer is 7.29π m
`m^(2)`
