The sphere is centered in the cube. Find an expression for the volume of the cube outside the sphere
Nikolay [14]

Solution -

The sphere is centered in the cube, so diameter of the sphere is equal to the side of the cube. Hence ,the radius of the sphere is half of the length of the side.

If the length of side of the cibe = a , then radius of the sphere is \frac{a}{2}

Volume of the cube = a³, volume of the sphere = \frac{4}{3}π(radius)³ = \frac{4}{3}π(\frac{a}{2})³

volume of the cube outside the sphere = volume of the cube - volume of the sphere

=  a^3 - \frac{4}{3}π(\frac{a}{2})³

= a^3 -\frac{1}{6} \pi a^{3}

=a³(1 - \frac{\pi }{6})

1. If you wanted to make a triangle with side lengths of 3 units, 3 units, and 4
ivanzaharov [21]

Answer:

Since 4 is the largest number its the hypotenuse. The two 3s are equal so they are interchangeable so it doesn't matter where you put them. If its a right triangle the hypotenuse is opposite the right angle.
