(Pi* r^2) = the area of the circle, or cross section

= 201.06

Multiply by the height for volume, *12

= 2412.74 -- this is the total volume

now *2/3 to get the answer

=1608.5

I dont know what the units are, they aren't given

Find the area of the triangle...

Alekssandra [29.7K]

In order to find height (h), tan20 = h/26
$h = 26 \tan(20) = 9.46$
Now for the left part of base (b1), where b2 = 26 and entire base (b) = b1+b2
$\tan(36) = h \div b1 \\ b1 = 9.46 \div \tan(36) = 13.03$
So b = 13.03+26 = 39.03

Now Area (A) = 1/2bh = 1/2 (39.03)(9.46)
A = 184.59
