Please help me if you know how to do it

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with

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.
