The length of a rectangle is 10cm, the width is 3cm, take the length as the axis, rotate a circle to get a cylinder, calculate the volume of the cylinder
3.14*10*10*3=942
So it's 942 cubic centimeters
A rectangle is 8cm in length and 3cm in width. Take the length as the axis and rotate one circle to form a cylinder?
Bottom radius = width = 3cm
Bottom area = 3.14x3 & # 178; = 28.26cm2
Volume = 28.26x8 = 226.08m3
