Answer: 603 cubic inches

Step-by-step explanation:

Let's find radius (r):

Diameter is double the radius, so the radius is 4 inches.

Let's find the height (h):

Height is 3 times the radius so the height is 12 inches.

Now let's find the volume:

V = πr^2 × h

V = π × 16 × 12

V = 603 cubic inches

tresset_1 [31]

Answer:

B) When Y = 90

X = 90 x -3

= -270

C) When X = -8

Y = 33.6(approx.)

D) When Y = 12.6

X = 12.6 x 3

= 37.8

Hope this helps!
