3. Given parameters b and h which stand for the base and the height of an isosceles triangle (i.e., a triangle that has two equal sides), write a C program that calculates: The area of the triangle; The perimeter of the triangle; And The volume of the cone formed by spinning the triangle around the line h The program must prompt the user to enter b and h (both of type double) The program must define and use the following three functions: Calc Area (base, height) //calculates and returns the area of the triangle Calc Perimeter (base, height) //calculates and returns the perimeter Calc Volume(base, height) //calculates and returns the volume
