If the ratio of radius of two spheres is 4:7, the ratio of their volume is?​
Kazeer [188]

Answer:

64 : 343

Step-by-step explanation:

First use the radii to find the volume

1) Radius of first sphere is 4 (taken from 4:7 ratio)

   Insert it into the equation for volume of a sphere: V=4 /3πr^3

   V = (4/3)(π)(4^3)

   V = (4/3)(π)(64)

   V = 256/3 π

   Volume of the first sphere = 256/3 π

2) Radius of the second sphere is 7 (also taken from 4:7 ratio)

   Insert it into the equation for volume of a sphere: V=4 /3πr^3

   V = (4/3)(π)(7^3)

   V = (4/3)(π)(343)

   V = 1372/3 π

   Volume of the second sphere = 1372/3 π

Next, calculate the ratio by dividing the two numbers

256/3 π ÷ 1372/3 π

Answer should be 64 : 343

The simple way to do this problem is to just cube the numbers:  

4:7 becomes 4^3 : 7^3 = 64 : 343

Either way works.

If Becky reads at a rate of p pages per hour for a total of h hours, which of the following represents the total number of pages
Elis [28]

We are looking for the total number of pages Becky reads, which is dependent on how many hours she reads for. So, we should multiply the number of pages she reads by the number of hours.

The correct answer is p x h or h x p. As long as these two values are multiplied, there is no difference in the order of the values.

Hope this helps!! :)
