Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is \pi r^2 h/3. If the radius is doubled, the new volume will be \pi (2r)^2h/3, which is equal to 4\pi r^2h/3. This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is \pi r^2 h/3. If the height is doubled, the new volume will be \pi r^2(2h)/3, which is equal to 2\pi r^2 h/3. This means that the volume is multiplied by 2.

svetlana [45]

Answer:3 cups of seeds and 2 tablespoons of maple syrup

-OR-

6 cups of seeds and 4 tablespoons of maple syrup

Step-by-step explanation:

As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"

The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"

Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.
