First you should find the area of the rectangle in the middle.
A: 9 x 6 = 54
Then you can find the area of the triangle on the right.
A: 6 x 5 = 30/2 = 15
Then you can do the triangle on the right.
11-9 = 2
A: 2 x 6 = 12/2 = 6
Then you can add it all together.
15 + 6 + 54 = 74
So the area of the irregular shape is 74.

I hope this helps!

Answer:

<h2>V = 235.5 in³</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3

\pi\approx3.14

Therefore

x=(75)(3.14)=235.5\ in^3
