帮我解一道英语数学题

find the solid volume of area bounded by the curve y=x^2 and the line y=4 generates rotated by y-axis~

It is a calucus problem.

V = integration symbol(0 to 4) A(y)dy
= integration symbol(0 to 4) pi * y^(1/弊茄羡2) dy
= 2/租拍纳闭3 pi * y^(3/2) ](0 to 4)
= 16/3 pi - 0
= 16/3 pi

i took calculus few years ago, if you i remember well then that should be answer.

找出被曲线y=x^2，直线y=4和y轴围起来的阴影部分~
应该就是这样~
