Answer:
43.35pi m cubed
Step-by-step explanation:
Volume of a cylinder
= pi r^2 h
Where r = radius
h = height
Given r = 1.7m and
h = 15m
Volume = pi x (1.7)^2 x 15
= pi x 1.7 x 1.7 x 15
Multiply through
Volume = 43.35 pi m cubed

Answer:
13x^2 - 18x + 9
Step-by-step explanation:
<u>Step 1: Distribute the plus and minus signs</u>
(4x^2 - 5x + 6) + (9x^2 - 2x) - (11x - 3)
4x^2 - 5x + 6 + 9x^2 - 2x - 11x + 3
<u>Step 2: Combine like terms</u>
4x^2 <u>- 5x</u> <em>+ 6</em> + 9x^2 <u>- 2x</u> <u>- 11x</u> <em>+ 3</em>
13x^2 - 18x + 9
Answer: 13x^2 - 18x + 9
