REALLY IMPORTANT
The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 24 cubic units. What’s the height of the cylinder?

2 units
4 units
6 units
8 units

Step-by-step explanation:

h = 3r

πr²h= 24π cubic units

πr²*(3r) = 24π

π*r³*3 = 24 π

r= 2 units

Height = 3*2 = 6 units

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

answer: 7270
