Answer:
8:27
Step-by-step explanation:
1 way to do it is...
The volume of a sphere is 4/3*pi*r^3. Plugging in 2 and 3 in for the radii you get the volumes are about 33.51 and 113.1, which is an 8:27 ratio.
Another way to do it is...
The ratio of the radii is 2:3 and a radius is 1-dimensional. The volume, however is 3-dimensional. To get from 1-D to 3-D, you have to cube the numbers. 2^3 is 8 and 3^3 is 27, so the ration is 8:27.
Answer:
after 3.92 seconds
Step-by-step explanation:
Fill in the given value of h to find the formula for the height of the ball. Then set the value of that height to zero and solve for t.
Ball 2 reaches the ground after 3.92 seconds.
Answer is 11/6
Hope this helps :)
Angle 1 = 2x - 30
angle 2 = x
2x - 30 = x
2x - x = x
x - 30 = 0
0 + 30 = 30
x = 30
