198 = 5X:X = A:B
198 = 5X + X = 6X
X = 198 / 6 = 33
A = 33*5 = 165mph
B = 33*1 = 33mph
Surface area = 50 x 30 = 150
Per cm of height 150 cubic cm needed
7cm height needed
150 x 7 = 1050 cubic cm needed
Answer:
19.6 cubic centimeters
Step-by-step explanation:
The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.
Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is
.
We also know the actual volume of the larger cone is 66. So, if x is the volume of the smaller cone, we have the proportion:
x / 66 = 8 / 27
Cross-multiply:
27x = 66 * 8 = 528
Divide by 27:
x = 528/27 ≈ 19.6
The answer is thus 19.6 cubic centimeters.
