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

 1507m²

Step-by-step 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

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
