The volume of a cube can be expressed as
Let V = volume
Let a = side length
V = a^3
We need to solve the formula to isolate the variable a. First, we must cube root each side.
∛(V) = a. With our new formula, we plug in 64 cube inches into V.
∛(64) = a.
4 = a.
The length of one side on our cube is 4 inches.
It depends what inequality you have
Answer:
1130.4 mm
Step-by-step explanation:
Given,
Radius ( r ) = 180 mm
To find : Circumference of the pulley ( C ) = ?
Formula : -
C = 2πr
Note : -
Value of π is 3.14
C = 2 x 3.14 x 180
C = 1130.4 mm

To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²

The answer is: 2,158 m²
