Question

find the curved surface area of a right circular cylinder whose height it is 13.5cm and radius of its base is 7 cm also find its total surface area​

Answer 1

Step-by-step explanation:

Given: h=13.5cm.

r=7cm

$csa \: of \: cylinder = 2 \times \pi \times r \times h$

CSA =2*22/7*7*13.5

=44*135/10=594cm².

$tsa \: of \: cylinder = 2 \times \pi \times r(r + h)$

TSA= 2*22/7*7(7+13.5)

=44*205/10

=902cm².
