Me because i don't understand how to do it.: )

V =84.78 inches ^2

Step-by-step explanation:

The volume of a cylinder is given by

V= pi *r^2 h

We know h= 12 inches

and r = 1.5 inches

V = pi * (1.5)^2 * 12

V = pi * 2.25*12

V = 27 pi

If we approximate by 3.14

V = 3.14 (27)

V =84.78 inches ^2

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
