Need with the last question !

Calculate the area of the whole figure to obtain the amount flooring carpet required.

So

area of circle = πr²

area of square = side × side

add them in the end.

area of circle = 3.14 × 20× 20 = 1256 ft

area of square = 40× 40 =1600

total area = 1600 + 1256 = 2856 ft

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
