Question

A cylindrical container, open at the top,has the base radius 14cm and height 20 cm find its total surface area.​

Answer 1

Answer:

2376 cm^2

Step-by-step explanation:

Radius = 14 cm

Height = 20 cm

Total Surface Area of cylinder = 2$\pi$r(h+r)

= 2 * 22/7 * 14 (20+14)

= 2992 cm^2

It is open at the top so, its total surface area

= 2992 - $\pi$r^2

= 2992 - 22/7*14*14

= 2992 - 616

= 2376 cm^2 Ans.
