Answer:
Step-by-step explanation:
Let's use the integral formula for the surface area of revolution of the function y(x) around the x-axis, which is:
and which in our case, we can obtain the following:
Recall as well that , which gives us the limits of integration:
If we compare it with the geometry formula:
Lateral surface of cone =
which is exactly the expression we calculated with the integral.
Answer: 1 1/12
Step-by-step explanation:
1/3 + 3/4 =
1/3 x 4= 4/12
3/4 x 3 = 9/12
9/12 + 4/12 = 13/12 = 1 1/12
