Regina is building a hot tub next to her swimming pool the interior dimensions are 6 feet by 7.5 feet it includes a solid bench seating on all four 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?

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
