A NEW OG 2021 QUESTION
Volume of Tank A (VA) = pi * (R1)^2 * H1
Volume of Tank B (VB) = pi * (R2)^2 * H2
Circumference (A)=8
=> 2*pi* R1 =8=> R1 = 8/2*pi and similarly R2 = 10/2*pi
Substitute these values in VA/VB to have
VA/VB
= (R1)^2 * H1/ (R2^2 * H2)
= 8^2 * 10 / (10)^ 2 * 8
= 8/10
=> VA/VB =8/10 = >VA is 80% of VB (OPTION B)
Tanks A and B are each in the shape of a right circular cylinder. The interior of Tank A has a height of 10 meters and a circumference of 8 meters, and the interior of tank B has a height of 8 meters and a circumference of 10 meters. The ca Print
