PLEASE HELP WITHIN THE NEXT FEW MINUTES!

Lianne drew a sphere with a radius of 7 in. She calculated its volume and wrote it below. ? pi/3in cubed. What value should be multiplied by pi in the numerator to correctly show the volume of the sphere?

Answer 1

7 swhould be multiplied by pi

Answer 2

Volume of a sphere can be found by using the formula V=
`(4)/(3) \pi r^(3)` where r is the radius of sphere.

Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written
`(\pi)/(3)` and need to find what should be multiplied in numerator with pi.

`V=(4)/(3) \pi r^(3) =(4\pi r^(3) )/(3) =(\pi)/(3) (4 r^(3) )`

As r= 7 she needs to multiply numerator
`4 r^(3) = 4 (7^(3)) =4(343) =1372`

The number to be multiplied is 1372.
