Question

C.S.A of a cylinder of base radius 7 cm and height 25 cm is​

Answer 1

Answer:

1100cm^2

Step-by-step explanation:

Curved Surface area of cylinder =2πrh

Given:

radius =7cm

height=25cm

Curved Surface Area =2×22/7×7×25

=2×22×25

=1100cm^2

Answer 2

Answer:

$\huge\bf\red{Given}$

Curved Surface area of cylinder =2πrl

$\huge\bf\orange{Formula}$

R=Radius= 7cm

L= height = 25cm

$\huge\bf\pink{Calculation}$

Curved Surface area of cylinder =2 x $\frac{22}{7} \times 25cm$

=50 x 22 cm²

Curved Surface area of cylinder =$\boxed{1100cm²}$
