Question

please answer with explanation only Q 10

Answer 1

(a)C.S.A of cylinder=308
2pie r h=308
2x22/7xrx14=308
88xr =308
r =308x1/88
r =3.5

volume of cylinder=pie r^2h
=22/7x3.5^2x14
=22x12.25x2
=539cm

(b)volume of cylinder=1540
pir r^2h=1540
22/7x7^2xh=1540
22/7x49xh=1540
h=1540x1/7x1/22
h=10cm

C.S.Aof cylinder=2pie r h
=2x22/7x7x10
=440cm^2


hope it hlps u
