The child's physical density is being measured by the displacement method. a child of 50 pounds is place in a tub filled with water, and the water that comes out of the tub goes in to another small tub that measures 40 cm long, 30 cm wide, and 60 cm deep. the water level in the small is 18 cm high. find the density of the child's in gn/cm^3 to the nearest hundredth. (hint: density=mass/volume; 1 pound= 454 grams

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.
