Question

2. Find volume (V) and curved surface area (A) of the right circular cylinder having
the radius of the circular base (r) and height (h) as:
(iii) r=3.5 m, h = 14 m
(iv) r = 0.35 m, h = 1.25 m​

Answer 1

Answer:

radius= 3.5

height= 14

volume= πr^2h

= 22/7 ×3.5×3.5×14

= 539m^3

C.S.A= 2πrh

= 2×22/7×3.5×14

= 308m^2

radius= 0.35

height= 1.25

volume= πr^2h

= 22/7×0.35×0.35×1.25

= 0.480m^3

C.S.A= 2πrh

= 2×22/7×0.35×1.25

= 2.75m^2

Answer 2

Step-by-step explanation:

For a Cylinder

r = 3.5m n=14m

Volume = π r^ 2 h

=22/7×(3.5)2×14

= 22 /7 x 3.5X3.5X14

= 22x3.5X3.5X2

=539m3

Curved surface area =2πrh

=2x22/7x3.5×14

=2X22X3.5x2

= 308m²
