Find the lateral area and the total surface area of a right

Find the lateral area and the total surface area of a right cone with a diameter and slant height of 4 inches. Lateral Area = _______ Total Surface Area = __________ Find the total surface area and the volume of a right cone with a radius of 3 inches and a height of 4 inches. Total Surface Area = _________ Volume = ________ Find the radius of the oblique cylinder. __________

Solution

12.

SA = r² + rl

lateral surface area = rl = pi *2*4 = 8

Total surface area = 8 +*2^2 = 12
