... is surrounded by a hemisphere of radius r.a. Find a polynomial in the variable r that represents the volume of the quot;siloquot; shape.b. Find a polynomial in r that represents the total surface area of the silo.
A right circular cylinder whose radius is r and whose height is 2r is surrounded by a hemisphere of radius r. a. Polynomial in the variable r that represents the volume of the silo shape is given by V = pir^2[2r + (4/3)r] = (10/3)pir^3 ANSWER b. Polynomial in r that represents the total surface area of the silo is given by S = 2pir(r + 2r) + 4pir^2 = 10pir^2 ANSWER.
