First you would solve for h(5) by plugging in 5 as your x, then solving it.

h(5) = 5^2 + 1
h(5) = 25 + 1
h(5) = 26

Next you would multiply the 26 by the individual h, which is basically h(1).

h(1) = 1^2 + 1
h(1) = 2

Lastly you multiply your h(1) value by the h(5) value to get your answer.

h(1) • h(5) = 26 • 2
h[h(5)] = 52

Answer:

24501.42 cubic meters

Step-by-step explanation:

Volume of a cylinder

= pi r^2 h

Given diameter = 34

radius r = diameter/2

= 34/2 = 17

So radius r = 17

Height h = 27

Pi = 3.14

Volume = 3.14 x (17)^2 x 27

= 3.14 x 17 x17 x 27

Multiply through

= 24501.42 cubic meters
