A silo has a cylindrical part and a roof that is a hemisphere. The radius of the
cylinder is 3 m and its height is 12 m.
a Find the volume of the silo.
b The entire silo is to be painted. Find how
much paint is needed if 1 L of paint cover
8.5 m2 of surface.​

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.
