Question

Please help me out with this please

Answer 1

5.4 ft²

Explanation:

The area of the yellow region = area of square - area of circle

area of square = 5² = 25

note that the diameter of the circle = 5, thus radius = 2.5

area of circle = π × 2.5² = 6.25π

yellow region = 25 - 6.25π ≈ 5.4 ft²

Answer 2

The area of a circle is

`a = r {}^(2) \pi`

So we get

`a = 2.5 {}^(2) \pi`

so we get 19.6 rounded to the nearest tenth

Now we subtract that from the area of the square which is 25

We get 5.4

So the answer shoild be 5.4ft

Hopefully this is correct and helps you!
