(ANSWER QUICK PLS) What is the surface area of a can that has radius of 9 ft. and height of 3 ft.? Use 3.14 for pi. SA : ? ft^2
A. 678.2
B. 354.3
C. 292.0
D. 458.6

The surface area would be A. 678.2

Step-by-step explanation:

A = 2 (3.14) (9) (3) + 2 (3.14) (9)^2

  = 169.56 + 508.68

  = 678.24

The correct answer is A!

Correct

678.2  

Step-by-step explanation:

Remember,  π = pi = 3.14

To find the surface area you need to use the expression: 2πrh + 2πr

Substitute the variables (the variables are π, r, and h), turning them into equations in parentheses beside the two numbers (the numbers used in the equation is 2):

2(3.14 x 9 x 3) + 2 (3.14 x 9)

Finally complete the equation.

3.14 x 9 x 3 = 84.78

3.14 x 9 = 28.26

2(84.78) + 2(28.26) = 678.2

So the answer is 678.2.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
