Question

radius of base of a cylinder and it's height are given find the curved surface area and total surface area r=1.4 h=2.1

Answer 1

Answer:

Step-by-step explanation:

Given radius of cylinder=1.4m

h=2.1m

C.s.A of cylinder =2πrh

=2π(1.4)(2.1)

=18.46m

T.S.A of cylinder=2πr(r+h)

=2π(1.4)(3.5)

=30.7m
