Question

A cylinder has a radius of 12 m and a height of 8 m. What is the approximate surface area of the cylinder? Use 3.14 for π. Use your calculator to solve.

Surface area of a cylinder can be found using the formula SA = 2πr2 + 2πrh.

Question 2 options:

904 m2


1507 m2


7837 m2


8139 m2

Answer 1

it is B.) 1507 m2

Explanation:

Because i took the test

Answer 2

1507m²

Explanation:

Given parameters:

Radius of cylinder = 12m

Height of cylinder = 8m

π = 3.14

Unknown:

Surface Area of cylinder = ?

Solution:

The surface area of any body is the sum of all the area that covers a body.

For a cylinder, the surface area is given as;

SA = 2πr² + 2πrh

Where SA = Surface Area

r = radius of cylinder

h = height of cylinder

Now input the parameters in the given equation and solve;

SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)

SA = 904.32‬ + 603.264‬

SA = 1507.584‬m² = 1507m²
