Answer:

Step-by-step explanation:

-9x - 15y = -6

9x + 11y = 14

-4y = 8

y = -2

3x - 10 = 2

3x = 12

x = 4

Answer:

y = -3/5x +2 y = -9/11 + 14

Step-by-step explanation:

3x + 5y = 2(subtract 3x on both sides)

5y = -3x +2(divide by 5)

y = -3/5x + 2

9x + 11y = 14 (subtract 9x on both sides)

11y = -9x + 14 (divide by 11)

y = -9/11x + 14

Find the volume of the cylinder if the height is 3 mm and the diameter is 40 mm. Leave the answer in terms of it.

KiRa [710]

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.

Step-by-step explanation:

Height of cylinder = 3mm

Diameter of cylinder = 40mm

Volume of cylinder = ?

The formula used to find Volume of cylinder is:

$Volume = \pi r^2h$

Putting values in the formula:

Since we need radius,

radius = diameter/2

radius = 40/2

radius = 20 mm

So,

$Volume = \pi r^2h\\Volume = 3.14*(20)^2*3\\Volume = 3.14*400*3\\Volume= 3769.91 or \,\,\,Volume\approx 3770\,\,cubic\,\,millimeters$

The Volume of cylinder is 3770 cubic millimeters

But, the correct option is not available in options given.
