A. 3 : 7
B. 7 : 3
C. 6 : 7
D. 7 : 6
Answer:B
A cylindrical pillar has a curved surface area of 264 m2 and a volume of 924 m3. Calculate the diameter to height ratio.
A. 3 : 7 B. 7 : 3 C. 6 : 7 D. 7 : 6
Explanation: r2h/2rh = 924 /264 7 m = 924 x 2 /264 = 924 x 2 /264 = 924 x 2 /264 = 924 x 2 /264Furthermore, 2rh = 264 h = 264 x 7/22 x 1/2 x 1/7 = 6m.2r/h = 14/6 = 7:3 is the required ratio.
