What is the ratio for the volumes of two similar cylinders, given that the ratio of their heights and radii is 3: 7?

The ratio is or 27:343

Step-by-step explanation:

The volume of cylinder is = ; where r is radius and h is height.

Given that the ratio of the heights and radii of two similar cylinders is 3 : 7.

Let r' be the radius and h' be the height of the other cylinder.

Its volume is

According to the given information, we have

Hence, we get

=

=

Therefore, the ratio is 27:343

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
