**The radius of a cylinder is 14 cm. Its height is 20 cm. Find out its volume,**

**curved area and total surface area.**

**Solution:** Volume of cylinder = π r^{2} h

= π x 14^{2} x 20

= 3920 π cm^{3}

Curved surface area = 2 π r h

= 2 x π x 14 x 20

= 560 π cm^{2}

Total surface area = 2 π r (h + r)

= 2 x π x 14 (20 + 14)

952 π cm^{2}
