Question

Find the total surface area of closed right circular cylinder whose radius of base is equal to 9 cm and height 35 cm.​

Answer 1

hey!

given

radius = 9cm

height= 35 cm

total surface area of cylinder = 2πrh+2πr^2

=2πr(h+r)

=2×22/7×9(9+35) cm^2

=44/7×9×44

=2489.14 cm^2

Answer 2

Answer:

Step-by-step explanation:

First of all You need to know that what is the formula of TSA(Total Surface area) of Cylinder.That is

2×22/7*r(r+h)

We are given that-

Radius-9cm

Height-35cm

So simply put this values in formula

TSA of cylinder=2×22/7×9(9+35)

=2×22/7×9×44

=17424/7

Answer-2489.14cm^2
