A cylinder is 8.2 inches high and has a diameter of 8.2 inches. Find the volume to the nearest tenth. Use 3.14 for pie

The volume to the cylinder is 433.8 in³

Step-by-step explanation:

To solve this problem we have to know that to calculate the volume of the cylinder we have to multiply the base by the height.

The base of a cylinder is circular, so we have to calculate its area with another formula.

The area of a circle is calculated with the following formula:

r = d/2

r = 8.2 / 2

r = 4.1 in

a = π * r ²

a = 3.14 * 4.1²

a = 52.7834 in²

The volume of a cylinder is calculated with the following formula:

h = 8.2 in

v = a * h

v = 52.7834 in² * 8.2 in

v = 432.82388

round to de nearest tenth

v = 433.8 in³

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.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
