hi
if the radius of the base of a cylinder is 21 m and its height is 15 metre then find its curved surface area
Please solve step by step​

Answer 1

cylinder..

r=21m

h=15m

CSA=

$2\pi \: r \: h$

$2 \times \frac{22}{7} \times 15 \times 21$

$2 \times 22 \times 15 \times 3 \\ \\ 1980 \: {m}^{2}$

$\huge\mathfrak\red{Thanks}$

Answer 2

Answer:csa=2πrh

Step-by-step explanation:2*π*21*15

=1980
