<span>r' = 4
Since all circles are similar to each other. Such as the radius always being half of the diameter. The ratio between the diameter and the circumference being pi, etc., we have plenty of information to calculate C, d, and r for both circles.
C/C' = 0.75 was given to us. So we know that d/d' is also 0.75. So let's write that equation and solve for d'
d/d' = 0.75
6.0/d' = 0.75
6.0 = 0.75d'
6.0/0.75 = d'
8 = d'
And r' will be half of d', so 8/2 = 4. Therefore r' = 4.</span>
Answer:c) they have the same volume
Step-by-step explanation: same height equals same volume
Answer:
3/14
Step-by-step explanation:
P=3/(3+4+7)=3/14 because each of 14 marbles is equally likely to be drawn.
Hope this helped :)
Have a great day!
The answer is 2/16 if you do the math with the numerators only.
5x - 2x + 8 = 2 + 6x + 6
Add like terms:
5x - 2x = 3x
2 + 6 = 8
3x + 8 = 6x + 8
To isolate the variable, subtract 6x from both sides of the equation:
3x - 6x = -3x
-3x + 8 = 8
Now subtract 8 from both sides:
8 - 8 = 0
-3x = 0
To finish, divide both sides by -3:
0 ÷ -3x = 0
The answer is x = 0
Hope this helps.
