Answer:
64:27
Step-by-step explanation:
If the ratio between the old and new radius is described with the ratio: 4:3, then if the first radius was 3, then the new radius is 4.
Also if you multiply 3 by (4/3) it also equals 4
The volume of a sphere is described as: [tex]\frac{4}{3} \pi r^{3}[/tex]
So let's plug in 3 and 4 and see their ratio.
[tex]\frac{\frac{4}{3}\pi 4^{3} }{ \frac{4}{3}\pi 3^{3} }} = \frac{4^{3} }{3^{3} } = \frac{64}{27}[/tex]
The answer is 64/27 or (4/3)^3
Answer:
by a factor of 64/27 or 64:27
Step-by-step explanation:
Volume of a sphere = 4/3 pi r^3
now increase the radius by 4/3 ( this is 4:3)
new volume = 4/3 pi (4/3 r)^3
= 64/27 * 4/3 pi r^3
so the original volume is increased by 64/27
