6/10 its adjacent over hypotenuse

N x (4/5) = (3/4)

(4/5)N = (3/4)

Divide both sides by 4/5 (cross multiply, 3 times 5, 4 times 4)

N=15/16 = 0.938

**Answer:**

9/2π

=14.13716694

**Step-by-step explanation:**

The equation of the volume of the sphere:

V=4/3πr^3

If the diameter is 3cm, the radius is divided by 2, so 1.5cm.

Plug that in, 4/3π1.5^3
