Given,

Diameter of Cylinder = 20 cm
Radius (r) = 20/2 cm = 10 cm
& Height (h) = 25 cm

 =  > t.s.a = 2 \pi r(r + h)

 =  > t.s.a = 2 \times  \frac{22}{7} \times 10(10 + 25)

 =  > t.s.a = 2 \times  \frac{22}{7} \times 10 \times 35

=> T.S.A =( 2 x 22 x 10 x 5) cm^2

=> T.S.A = 2200 cm^2

Answer:


Step-by-step explanation:

TSA OF CYLINDER=2 PI RH+2 PI RSq

R=20/2=10

=2*22/7*10*25+2*22/7*10*10

=1100/7+4400/7

=5500/7

=785.714 square cm


Likhit07: different ans u have got I think
TIMESHANI: i may be wrong
Likhit07: k check it
priyabelur123paze5f: it is right but there is mistake in decimal places. it is 7857.14
