Answer:

sin²Ф

Step-by-step explanation:

I doubt that you actually meant "cos 0" ... that has a value of 1.

If you meant (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.

That, in turn, is equal to sin²Ф

How to find the volume of a quarter-sphere?

Ganezh [65]

As the word suggests, a quarter-sphere is a quarter of a sphere, and thus the volume of a quarter-sphere is a quarter of the volume of the sphere.

The volume of a sphere is computed as

$\dfrac{4}{3} \pi r^3$

So, the volume of a quarter-sphere is

$\dfrac{1}{4}\cdot \dfrac{4}{3} \pi r^3 = \dfrac{1}{3} \pi r^3$
