Hello.

When dividing fractions, you never actually divide. You actually flip the second fraction, then multiply.

So, to convert this into a multiplication problem, we flip the second fraction, which is 4/7, then replace the division sign with a multiplication sign.

The problem is now 3/11 x 7/4. None of the fractions can be simplified, so we multiply. Multiply across the top and bottom. (3 * 7 = 21) - (11 * 4 = 44)

We end up with 21/44. It cannot be simplified, so this is our final answer.

Hope this was helpful!

What is the volume of a cylinder, in cubic centimeters, with a height of 7 centimeters

devlian [24]

Answer:

The volume of a cylinder is $1782\ cm^3$ .

Step-by-step explanation:

We have,

Height of cylinder, h = 7 cm

Diameter of cylinder, d = 18 cm

Radius, r = 9 cm

It is required to find volume of cylinder. The formula of the volume of cylinder is given by :

$V=\pi r^2h\\\\V=\dfrac{22}{7}\times (9)^2\times 7\\\\V=1782\ cm^3$

So, the volume of a cylinder is $1782\ cm^3$ .

PLEASE HELP IK ITS SO HARD TO UNDERSTAND FOR MEEE

Minchanka [31]

Answer: 15

Step-by-step explanation:

First step is to find the slope of the line given

y = -x - 2

y = mx + c where m is the slope of the line so the slope of the line is -1

If 2 lines are perpendicular to one another, the product of the slopes is -1 so the slope of the perpendicular line is -1/-1 = 1

y = 1x + c or y = x + c

As the line passes through the coordinate (-5,10), we can substitute the x and y value of the coordinates into the equation

10 = -5 + c

c = 15

So the equation of the line is y = x + 15
