Cylinders Q and P are both right circular cylinders. The height of cylinder Q is 3 times the height of cylinder P, and the radiu
Helen [10]

Answer: The volume of cylinder Q is 12 times the volume of Cylinder P.

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

If cylinder Q has radius, r and height, h,

Then

Volume of cylinder Q = πr²h

For cylinder P,

Height = 3h

Radius = 2r

Volume of cylinder P = π(2r)² × 3h

= 4πr²× 3h = 12πr²h

Therefore, the ratio of the volume of cylinder P to the volume of cylinder Q is

12πr²h/πr²h = 12

WHAT IS THE SLOPE OF THE LINE PASSING THROUGH THE POINTS (-2, -7) AND (3, 5)?????? PLZ ANSWER QUICKLY!!​
jarptica [38.1K]

Answer:

The slope of the line with points A(-2, -7) and B(3,5)  is  m =  (12/5).

Step-by-step explanation:

The two pints are given as A(-2, -7) and B(3,5)

Slope of a line with points (a,b) and (c,d) is given as

m =( \frac{d -b}{c-a} )

So, here the slope of line AB is

m =( \frac{5 - (-7)}{3 - (-2)} )  = \frac{5+ 7}{3 +2}   = \frac{12}{5}

or, m = 12/5

Hence, the slope of the line with points A(-2, -7) and B(3,5)  is (12/5).
