A small beach ball has a radius of 8 inches. A larger beach ball has a volume that is twice the volume of the small ball. What i
8090 [49]
V=(4/3)pir^3
find smaller
V=(4/3)pi8^3
V=(4/3)pi512
V=(2048/3)pi

twice of that
Vbig=2*(2048/3)pi
Vbig=(4096/3)pi
find radius
(4096/3)pi=(4/3)pir^3
divide both sides by pi
(4096/3)=(4/3)r^3
times both sides by 3
4096=4r^3
divide both sides by 4
1024=r^3
cube root both sides
8∛2=r
aprox
10.0794


the answer you are looking for is 8∛2 or 10.0794in or something close to that

Answer:

So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by  

2.5/1 .    Then, 20 x 2.5=50. So the answer is 50 km<-------------- Final answer

Hope this helps,
