Find the volume of the cylinder.
Either enter an exact answer in terms of a or
use 3.14 for a
units

volume of the cylinder = 150.72units³

Step-by-step explanation:

to find the volume of this cylinder  we are given that

radius  of the cylinder= 4units

height of the cylinder = 3units

volume of the cylinder =?

solution

recall that the fomular for finding the volume of a cylinder = πr²h

volume of the cylinder = πr²h

volume of the cylinder = 3.14 × (4)² × 3

volume of the cylinder = 3.14 × 16 × 3

volume of the cylinder = 3.14 × 48

volume of the cylinder = 150.72units³

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
