Question

A cylinder drum of the radius 7cm and height 14cm find C.S.A, T.S.A and volume of the drum​

Answer 1

Step-by-step explanation:

radius =7cm

height=14cm

csa=?

tsa=?

volume=?

we know that,

csa of cylinder =2 pi ×r×h

=2×22/7×7cm×14cm

=44cm×14cm

=616cm^2

tsa=2 pi×r (r+h)

=2×22/7×7cm×(7cm×14cm)

=44cm×21cm

=924cm^2

volume=pi r^h

=22/7×7cm×7cm×14cm

=154cm^2×14cm^2

=2156cm^3

Hope it helps

Answer 2

Answer:
C.S.A = 616cm^2
T.S.A = 924cm^2
Volume = 2156cm^3
Step-by-step explanation:
Radius = 7cm
Height = 14cm
C.S.A = 2πrh
= 2*22/7*7*14
= 616cm^2
T.S.A = 2πr(h+r)
=2*22/7*7(14+7)
= 924cm^2
Volume = Area of base * height
= πr^2h
= 22/7*7*7*14
= 2156cm^3
