Answer 1

TO SEE CLEARLY SEE THE PIC WHICH I ADDED

Now, the total surface area of a solid cylinder =616 cm

2

As per question,

[total surface area]=2

[curved surface area] =1

Now, the curved surface area=

2

616

=308

2πr

2

+2πrh=616

2πrh=308

2πr

2

=308

r=7

volume of the cylinder

V=πr

2

h

V=πrh×r

V=308/2×7

V=1078
