(Please Help Asap!) Find the volume of a cylinder having a height of 105 millimeters and a base with a diameter of 40 millimeters. Use the volume formula and 22/7 for π.

Choose the values for r and h. (1 H and 1 R)

h = 22/7
h = 105
r = 20
r = 40

132,000 millimeters squared, H= 105, R= 20

Step-by-step explanation:

Volume equation (r= radius, h = height)

v= (pie)x r^2 x h

Pie = 22/7

r = 1/2 the diameter, so 40/2= 20. r = 20

h = 105

Substitute

(22/7) x 20^2 x 105

20^2 = 400

(22/7) x 400 x 105 = 132,000

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
