Regina is building a hot tub for her swimming pool the interior dimensions are 6 feet by 7.5 feet. it includes solid bench seating on all for sides. the bench has a width of 1.5 feet. the bench is positioned 1.75 feet from the ground and 2.25 feet from the top. how many cubic feet of concrete is needed to build the hot tub?

its 69.420

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

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
