Question

The volume of Cylinder is 808 cm^2. Its height is 8 cm. Find its lateral Surface area and Total surface area.
​

Answer 1

Step-by-step explanation:

Volume of cylinder= πr^2h=808cm^2

h=8cm (given) value of π= 3.14

so, r=?

πr^2h=808cm^2

3.14×r^2×8=808cm^2

3.14×r^2=808/8

3.14×r^2=101

r^2= 101/3.14

r^2=32.16

r=√32.16

r=5.67cm

now, we will find LSA=2πrh

=2×3.14×5.67×8

=284.86cm^2(approx.)

now,TSA=2πr(r+h)

=2×3.14×5.67(5.67+8)

=35.60(13.67)

=486.65cm^2(approx.). Answer...
