Question

Find the total are of a cylinder whose radius is 14cm and the height is 20cm, if ir os closed on both sides

Answer 1

HELLO MATE

HERE IS YOUR ANSWER

TSA OF CYLINDER = 2πr ( h + r )

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

= 2 * 22 * 2cm * 34cm

= 88cm * 34cm

= 2992 cm²

HOPE IT HELPS.

Answer 2

Answer:

Step-by-step explanation:

To find the area of the cylinder

We know that Total surface area of cylinder = 2$\pi$r(r + h)

r[Radius] = 14 cm(Given)

h[Height] = 20 cm(Given)

Area = 2$\pi$r(r + h)

         = 2 X 22/7(As $\pi$ = 22/7 approximately) X 14(14 + 20)

         = 44/7 X 14 X 34(14 + 20)

         = 44 X 2 X 34

         = 88 X 34

Area  = 2992 $cm^{2}$(Total surface of the cylinder given in the question)
