How much paper will he need for one cone if his ice cream cone has a diameter of 6cm, and the slant edge is 15cm long?(the cone does not need a top) Give your answer correct to the nearest cm^2.

anonymous · Answer

The lateral surface area of a cone is L.A. = pi*r*l where pi = 3.14, r = radius of the cone, and l = slant height of the cone. L.A. = pi*3*15 = 45*pi = 141.37 = 142cm^2
