Consider a cylinder with a radius of 6 ft and height of 11.5

describe how to calculate the surface area of the given cylinder and what surface area means?

The formula for a cylinder V = pi r squared times the height. I should suppose you were told to abbreviate pi to 3.14. First do 6 to the power of 2 which is 36 then multiply it by 3.14 witch would be 113.04. Then multiply that by 11.5 which would be 1299.96

The answer is 1299.96
