- The curved surface area of a cylindrical pillar is 264 m2 and its volume is 924 m3.
Question 1:
The curved surface area of a cylindrical pillar is 264 m2 and its volume is 924 m3. Find the ratio of its diameter to its height. A. 3 : 7
B. 7 : 3
Feedback r=924/264x2 =7 m
h =(264 x7/22x1/2x1/7)= 6m.
Required ratio =2r/h=14/6 = 7:3
h =(264 x7/22x1/2x1/7)= 6m.
Required ratio =2r/h=14/6 = 7:3
C. 6 : 7
D. 7 : 6
