This should be relatively easy, since most of us have learned and used the formula for the volume of a sphere:  V = (4/3)* pi* r^3.

Just combine (4/3)pi into a single value, k, which results in   V = kr^3.

three numbers are in an arithmetic progression. Their sum is 3 and the sum of their squares is 11. what are the three numbers
Vlad [161]

The three numbers are 12, 18 and 24

Arithmetic progression

Let the 3 number in arithmetic progression be:

a-d, d, a+d ...

If their sum is 3, then;

a-d+d+a+d = 3

2a + d = 3 ........... 1

If the sum of their squares is 11, then;

(a-d)² + d² + (a+d)² = 11

a²-2ad+d²+d²+a²+2ad+d²  11

2a²+3d² = 11 ....... 2

Solving the equations simultaneously, d = 6 and a = 12

First-term = 12

second term = 18

Thirs term = 24

Hence the three numbers are 12, 18 and 24

Hope this helps you!!!!!! :D
