Hello,
Can you please tell me if my answer is correct here:
Right cylinder A has diameter 6 and height 5. Right cylinder B has diameter
10 and height 3. Which cylinder has the largest volume and what is the difference
between the two volumes?
(A) A's volume is greater than B's volume, and the difference is 30 pi
(B) A's volume is greater than B's volume, and the difference is 15 pi
(C) A's volume is equal to B's volume
(D) B's volume is greater than A's volume, and the difference is 15 pi
(E) B's volume is greater than A's volume, and the difference is 30 pi
I am getting E
Thanks,
Sri

Volume of Cylinder A = π 3²5 => 45π
Volume of Cylinder B = π 5²3 => 75π
Hence Volume of b > Volume of A by 30Ï€
Hence answer will undoubtedly be (E)

Volume of cylinder = (pi)r²hgmattesttaker2 wrote: Right cylinder A has diameter 6 and height 5. Right cylinder B has diameter

(A) A's volume is greater than B's volume, and the difference is 30 pi
(B) A's volume is greater than B's volume, and the difference is 15 pi
(C) A's volume is equal to B's volume
(D) B's volume is greater than A's volume, and the difference is 15 pi
(E) B's volume is greater than A's volume, and the difference is 30 pi
Right cylinder A: diameter 6 and height 5
This means the radius = 3
So, Volume = (pi)(3)²(5)
= 45pi
Right cylinder B: diameter 10 and height 3
This means the radius = 5
So, Volume = (pi)(5)²(3)
= 75pi
75pi - 45pi = 30pi
So, cylinder B has a volume that's 30pi greater than that of cylinder A
Answer: E
Cheers,
Brent
