The volume of the cylinder below is 225 pi cubic centimeters. If you doubled the radius of the of cylinder, which statement below would be true? *

The volume of the cylinder will be 900π cube cm.

Step-by-step explanation:

Given,

The volume of the cylinder 225π cube cm

Let the radius be r and the height be h.

To find the volume when the radius is doubled.

Formula

The volume of cylinder = π

According to the problem,

π = 225

When the radius is 2r the volume will be = π

=4π

=4×225π cube cm

= 900π cube cm

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
