Question

A cylinder has a radius of 16 m and a height of 9 m. What is the approximate surface area of the cylinder? Use 3.14 for π. A. 603 m2 B. 904 m2 C. 2512 m2 D. 14,469 m2

Answer 1

The formula for finding the surface area of a cylinder is as follows:

A = 2
`\pi rh` + 2
`\pi r^(2)`

Since we know the values of the radius and the height (and we know Pi = 3.14), we can plug these in to our formula and solve to find the surface area:

A = 2 (3.14) (16) (9) + 2 (3.14)
`16^(2)`

A = 904.32 + 1607.68

A = 2512

The approximate surface area of this cylinder is 2,512
`m^(2)`
