Find the volume of a sphere with a radius of 10.use pi or 3.14 to round to the nearest hundredth.

this is from khan academy so please help thanks !

4000/3 pi

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the radius is 10

V = 4/3 * pi * 10^3

V = 4/3 pi 1000

V = 4000/3 pi

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
