How do you find the total surface area of a closed cylinder?
Total surface area = (2*pi*radius2)+(diameter*pi*height)
Find the total surface area of this half sphere with a radius of 10?
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
Find the total surface area of this cylinder with a height of 10 and radius of 1?
Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units
Find the surface area of a hemisphere with a radious of 3?
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
