Figure is attached below:
Step-by-step explanation:
Given Data:
triangle vertices= A,B,C=(0,0), (7,0), (0,7)
Required: Find Volume of the solid=V=?
For this type of question we need to use the following formula of slicing method
where a and b are limits which shows that solid extends from
with the known cross section area
perpendicular to x-axis.
From the Figure.2 we can see that limits are from
to
and the red line is the diameter of the given semi circle.
We can see that if x increases then the diameter decreases along the hypotenuse thus diameter of the semi circle![=d=](/tpl/images/0511/6076/e2b40.png)
![7-x](/tpl/images/0511/6076/20250.png)
Radius is half of the diameter, so Radius of semi circle![=r=\frac{7-x}{2}](/tpl/images/0511/6076/f1044.png)
Here, Area
is the area of the semi circle
so![A(x)=\frac{1}{2}(\pi ) r^{2}](/tpl/images/0511/6076/5eadb.png)
Putting values, we get
Putting values in Eq(1), we get
Putting
we get everything zero that's why only have expression for value of
as:
