15 - 4 1/3 = 10 2/3
10 2/3 * 3/5 = 6 4/10
10 2/3 - 6 4/10 = 4 4/15
Answer: The volume is the sum of all the areas of the cross-sections.
The Area is the area of an equilateral triangle, where the length of the base is distance from curve 'x^2 + 1' and x-axis.
The height of an equilateral triangle is
Therefore Area of triangle is:
Now integrate to find Volume
Step-by-step explanation:
Answer:
a. is equal to -21
b. is equal to -1
c. is equal to 31
Step-by-step explanation:
a. 2(-2)²-5
-4²-5
-16-5
= -21
b.2(1)²-5
2²-5
4-5
= -1
c.2(3)²-5
6²-5
36-5
= 31
