The volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

<h3>What is a sphere?</h3>

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

We know the surface area of the sphere is given by:

SA = 4πr²

1465 = 4πr²

r = 10.79 cm

Volume of the sphere = 4πr³/3

V = 4π(10.79)³/3

V = 5262.03 cubic cm

Volume of five volleyballs = 5×5262.03 = 26310.15 cubic cm

Thus, the volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

the combined ages of jim, his father, and his grandfather equals 137. his grandfather is 70 years older than jim. and jim is 31
Andru [333]
---------------------------------------------------------------------------------------
Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31              ← Jim is 31 years younger than the father
Grandfather = x + 70     ← Grandfather is 70 years older than Jim

---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12

---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12

Father = x + 31
Father = 12 + 31
Father = 43

Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82

---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82

What is this equation called?
nadya68 [22]

\left\{\begin{array}{ccc}3x-6y=20&|\cdot2\\2x-4y=3&|\cdot3\end{array}\right\\\left\{\begin{array}{ccc}6x-12y=40\\6x-12y=9\\\end{array}\right

The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.

Answer: B. inconsistent.
