We manipulate the given equation in order to solve for EC. We do this by cross multiplying.
The resulting equation will be:
EC = (4 x 3)/5
EC = 12/5 = 2.4
Additionally, the side-splitter theorem works for this problem since DE and AC are parallel to each other, therefore splitting the remaining two sides into proportional segments.
7/10-1/2=←Write the equation
7/10-5/10=←Make it into a common denominator and subtract
2/10=←Simply if possible
1/5←This is the simplest form
<span>The trapezoid have vertices at (2,0), (2,2), (4,0), and (4,4)
and the rotation </span><span>about the x-axis.
the points (2,0), (4,0) are located on the x-axis
calculate the function y = m x + c using the other </span>vertices <span>(2,2), (4,4)
by substituting in the function y
m = 1 , and c =0
∴ y = x
</span>The volume can be calculated using

∴

∴

∴
Plastic sphere volume=4/3 times pi times rasius^3
4/3 times 3.14 times 18^3=24416.6
rubber ball whole=4/3 times 3.14 times 22^3=44579.6
subtract
44579.6-24416.6=20163
the answer is 20163 in^3
