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 :
(i) r = 5 cm, h = 21 cm

(ii) r = 7 m, h = 10 m

(iii) r = 3.5 m, h = 14 m

(iv) r = 0.35 m, h = 1.25 m ​

Answer 1

hope this helps u.........

Answer 2

R=7m

h=10m

volume = πr^2h

1. =22/7×7×10=1540
2. T. S A =2πrh
3. 2×22/7×10 =440
