Question

Pls help me i need number 35 pls

Answer 1

Explanation:

The figure below is made up of 2 quarter circles and a square.

`a _(total) = a _(square) +2 a _(quartercircle)`

The area of a square is

`{s}^(2)`

Area of a quarter circle is

`\frac{\pi {r}^(2) }{4}`

So our total area, is

`{s}^(2) + \frac{\pi( {r)}^(2) }{2}`

S is 5, and r is 5.

So we get

`25 + ((3.14)(25))/(2)`

`64.25`

Which is approximately D.

Answer 2

D. 64.3² in

Explanation:

Figure out the area of the shapes separately, then add them together. You have a square (5 x 5) and 2 quarter circles (which makes one half circle) with a radius of 5.

A-rectangle = 5 x 5 = 25

A-circle = πr² = (3.14)(5)² = 78.5

1/2 circle = 78.5 / 2 = 39.25

Total area = 25 + 39.25 = 64.25 ≈ 64.3
