Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are
We are given with an isosceles triangle having a vertex on the curve given y =<span>27-x^2</span> . The area of the triangle, A= xy = x (27-x^2) A' = 27-x^2-2x^2 = 0 x = 3 Amax = 3(27-9) = 54 units2
