The cylinder's total surface area is about 227.77 units2
If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).
Two hemispherical ends = 4*pi*radius2 Lateral surface area of the cylinder = 2*pi*r*lenght of cylinder Work both out separately and the sum of them will give you the total surface area in square units.
A cylinder with radius 4 and height 12 has a total surface area of 402.12 units2
A cylinder that has a diameter of 20 and height of 26 has a total surface area of 2,261.95 units2
A cylinder that has a radius of 1 and a height of 10 has a total surface area of 69.12 units2
Total surface area is 176 units2
r=7ft h=16ft
Total surface area = (2*pi*radius2)+(pi*diameter*height)
This cylinder has a total surface area of ≈ 1,156.11 square inches.
The volume of this cylinder would be 62.857142857142804 cubic units. The surface area of this cylinder would be 87.96459430051421 square units.
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
