Assuming that raduis = radius, the total surface area is 132 square units.
Total surface area of the cylinder: (2pi2^2)+(22pi4) = 68*pi square units or about 213.628 square units to 3 decimal places
If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).
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
1407.43 units2
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
113.10
The equation for measuring the lateral area (surface area excluding both the top and bottom faces) is 2 x radius x pi or the cylinder's circumference times its height. So, we just plug the numbers:2 x 3.1415927 x 5 x 8 = ~251.33
Total surface area is 176 units2
Assuming that shere = sphere and raduis = radius, the answer is 942 square units.
Total surface area = (2*pi*radius2)+(diameter*pi*height)
