If the ratio of radius two Cylinders A and B are in the ratio of 2:1 and their heights are in the ratio of 2:1 respectively.
Question 1:
If the ratio of radius two Cylinders A and B are in the ratio of 2:1 and their heights are in the ratio of 2:1 respectively. The ratio of their total surface areas of Cylinder A to B is?
A.2:1
B.1:2
C.1:4
D.4:1
FeedbackCylinder A: 2πr1 (r1 + h1) Cylinder B: 2πr2 (r2 + h2) r 1 /r 2 = 2:1; h 1 /h 2 = 2:1 T A /T B = 2πr1 (r1 + h1)/ 2πr2 (r2 + h2)
