1.) A vertical cylindrical storage tank, with a diameter 20 ft, is filled with oil to a depth of 40 ft. Sometime later, the oil is drained,decreasingthe depth at a rate of8 in per hour. Write anequationfor the volume of oil (ft^3) remaining in the tankthours later as afunction of,tV(t). Draw a geometrically correct sketch supporting your solution.

2.) The area of a series of isosceles triangles is modeled by a triangle that has its base along the positive x-axis, with one base angle at the origin and its vertex in the first quadrant, positioned on the graph of the functionf(x)=6-x^2. Write the area of the triangle as afunction of x,A(x). Make a suitable sized graphical sketch of the problem, showing relevant details supporting your solution.

thank you so much with the help :]
