Question

the circumference of the base of a cylinder is 88 cm and its height is 40 cm.Find its total surface area....plz plz plz solve this fast

Answer 1

Answer:

Total surface area= 4752 sq. cm

Answer 2

Let the base radius of the cylinder be r cm.

Height of its base = 60 cm

Circumference of its base = 88cm

circumference=2πr

88=2*22/7*r

r=88*7/2*22

=>r=14

Therefore, the radius is 14 cm.

Volume of the cylinder

=πr²h

22/7*(14)²*40

=3690cm
