Solution by Steps
step 1
To find the volume of the solid formed by rotating the area between y=x2y = x^2 and y=0y = 0 around the x-axis, we use the disk method
step 2
The volume VV of the solid is given by the integral V=abπr2dxV = \int_{a}^{b} \pi r^2 dx, where rr is the radius of the disk at a given xx, which is y=x2y = x^2 in this case
step 3
Substituting y=x2y = x^2 into the formula for volume, we get V=01π(x2)2dx=01πx4dxV = \int_{0}^{1} \pi (x^2)^2 dx = \int_{0}^{1} \pi x^4 dx
step 4
Using the asksia-ll calculator result, we have 01πx4dx=πx5501\int_{0}^{1} \pi x^4 dx = \frac{\pi x^5}{5} \Big|_0^1
step 5
Evaluating the integral from 00 to 11, we get π(1)55π(0)55=π5\frac{\pi (1)^5}{5} - \frac{\pi (0)^5}{5} = \frac{\pi}{5}
Answer
The volume of the solid is π5\frac{\pi}{5} cubic units.
Key Concept
