What is the surface area of the cylinder? Use 3.14 for pi and round your answer to the nearest hundredth.

Answers

Answer:

Surface area of the cylinder = 954.56 inches

Step-by-step explanation:

Given that

π = 3.14

height of the cylinder = 11in

radius of the cylinder = 8in

surface area of the cylinder = ?  

recall that,

surface area of the cylinder = 2πrh + 2πr²

surface area of the cylinder = 2 x 3.14 x 11 x 8 + 2 x 3.14 x 8²

surface area of the cylinder = 552.64 + 6.28 x 64

surface area of the cylinder = 552.64 + 401.92

Solve for x. Show your work 10=4(3a+2)

Answers

U mean solve for a?

10=4(3a+2)

10=(4)(3a)+(4)(2)(Distribute)

10=12a+8

Flip the equation.

12a+8=10

Subtract 8 from both sides.

12a+8−8=10−8

12a=2

 Divide both sides by 12.

12a/12=2/12

a=1/6

10=4(3a+2)
1: first you distribute the 4 to 3a and 2 (4*3a & 4*2)

10=12a+8

2: subtract the 8 from both sides

2=12a

3: divide the both sides by 12

1/6=1
