Question

A circular cylinder of height 40 cm its base radius is 3.5 cm find TSA LSA and volume

Answer 1

hey ! your answer is here

height = 40
radius= 3.5

total surface area of cylinder = 2 πrh +2 π r²
= 2πr(h+r)
= 2*22/7*3.5(40+3.5)
=957 cm²

lateral surface area of cylinder= 2πrh
= 2*22/7*3.5*40
= 880cm²

volume of cylinder= π r²h
= 22/7× 3.5×3.5× 40
=1540cm³

hope it helps

Answer 2

Given: 

r = 3.5 cm

h = 40 cm
___________________________________________________________

TSA of Cylinder = 2 πr (h+r)

                          = 2 × 22/7 × 3.5 (40+3.5)

                          = 957 cm²
___________________________________________________________

CSA of Cylinder = 2 πrh

                           = 2 × 22/7 × 3.5 × 40 

                           = 880 cm²
___________________________________________________________

Volume of Cylinder = π r²h

                               = 22/7 × 3.5 × 3.5 × 40

                               = 1540 cm³
