When the rectangle-xA0- is rotated the so obtained solid is cylinder-xA0-With height 7cm and radius 5cmVolume of cylinder is -x3C0-r2h227-xD7-5-xD7-5-xD7-725-xD7-22-550cm3

A rectangle of sides $5 c m$ and $7 c m$ are rotated along the side $7 c m$ Find the volume of solid so obtained.

When the rectangle is rotated the so obtained solid is cylinder
With height $7 c m$ and radius $5 c m$
Volume of cylinder is $π r^{2} h \frac{22}{7} \times 5 \times 5 \times 7 25 \times 22 = 550 c m^{3}$
