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

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
