The surface area of this cylinder to the nearest integer is? (height is 4 in. radius is 6 in.)

a) 57 in2.

b) 75 in2.

c) 132 in2.

d) 250 in2.

The surface area is equal to

Step-by-step explanation:

we know that

The surface area of the cylinder is equal to

where

B is the area of the base of cylinder

P is the circumference of the base of cylinder

h is the height of the cylinder

Find the area of the base B

we have

substitute

Find the circumference of the base

we have

substitute

Find the surface area

we have

substitute

the answer is 5/3x+7/5y+7

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
