Calculus Problems Volume
Need calculus (volume) problems checked!?
I’m not sure if any of these answers are right:
1)Volume of a solid formed by the boundaries: y=x^3 y=0 x=1 around the x-axis
answer: pi/7
2)Volume of a solid formed by the boundaries: y= -x+1 y=0 x=0 around the x-axis
answer: pi/3
3)Volume of a solid formed by the boundaries: y= x^(2/3) y=1 x=0 around the y-axis
answer: 3pi/7
1 and 2 OK
3. Should be 4pi/7.
You have found volume below the curve. Question asks for volume above curve and under y = 1.
