Find the geometric mean of 125 and 5..

Answers

The geometric mean of two numbers is the square root of their product.
GM = √( 125 · 5 ) = √ 625 = 25
Answer:
The geometric mean of 125 and 5 is 25.

Answer:

The geometric mean of 125 and 5 is, 25

Step-by-step explanation:

Geometric mean(GM) of two number is given by:

$GM = √(ab)$

As per the statement:

Given two numbers i.e 125 and 5

then by definition we have;

$GM = √(125 \cdot 5)$

⇒ $GM = √(625)$

⇒ $GM = √((25)^2)$

⇒GM = 25

Therefore, the geometric mean of 125 and 5 is, 25

The diameter of a soccer ball is 8.65 inches what is the volume of the ball rounded to nearest hundredth

Answers

A soccer ball is an icosahedron with curved faces that is why it can be regarded as spherical. The volume of a sphere is calculated through,

Vs = 4πr^3/3

where Vs is the volume and r is radius. From the given, 8.65 in is the diameter which is 4.325 in in radius.

Vs = 4π(4.325^3)/3 = 338.88 in cubed.

Thus, the volume of the ball is 338. 88 in cubed.
