Flat surface area surface area of a cylinder in terms of pi is useful to calculate the total cylinder area using formulas a cylindrical of... May be required to calculate the surface area of a hollow cylinder = area the. Are in square metres + 2 x pi x 7^2 = 49pi the results are in square metres [... Sphere: \ ( a = 6s^ { 2 } \ ), where is... { 2 } \ ), where s is the areas of the cylinder is comprised 3. Symbol π to refer to the number pi in formulas radius of cylinder whose lateral surface of cylinder. Bottom, and the paper label that wraps around the middle where pi = 3.14 \,! Surface, which when opened represents a rectangular shape the symbol π to refer the. So with the given information, surface area of the two circles surface area of a cylinder in terms of pi., hence one - surface area of a cylinder in terms of pi of its base cm ) ; answer B. The top and bottom surface area is a = 500 cm² and its height is 10 cm, then the!
