LSA =2 x pi x r x h
=2 x 22/7 x 7 x 20
=880cm^2
=2 x 22/7 x 7 x 20
=880cm^2
rupakramendra:
Lsa = 2pirh
Yes so I did that only.
So 2×22/7×7×20
So =880cm^2
I have already solved it
No problem

Given,
=> Radius of Cylinder = 7 cm
=> Height of Cylinder = 20 cm
As we know that there is a Formula to find out Lateral Surface Area.
=> L.S.A = 2πrh
=> L.S.A =( 2 x 22/7 x 7 x 20) cm^2
=> L.S.A = 880 cm^2
=> Radius of Cylinder = 7 cm
=> Height of Cylinder = 20 cm
