Question

find the
1)curved surface area
2)total surface area and
3)volume of a right
circular cylinder whose height is 15 cm and the radius of the base is 7 cm.

Answer 1

volume = 2310 cm3
curved surface area = 660 cm2
total surface area = 968 cm2

Answer 2

here's ur answer frnd!!!

1. CSA=2πrh

=2×22/7×7×15

=2×22×15

=660cm²

2. TSA=2πr(h+r)

=2×22/7×7(15+7)

=2×22×22

=968cm²

3.volume=πr²h

=22/7×7×7×15

=22×7×15

=2310cm³

hope this helps....
