n = amount of c-14 at time t
k = 0.0001
t = time, in years

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

Say it if the radius of a circle is 6 inches how long is the subtended by an angle measuring 70 degree

Find x. m just typing to fill the character minimum.
