Explanation:

This looks like an essay question with no right answer.

__

There are two "special" right triangles:

  isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2

  30°-60°-90° triangle with sides in the ratios 1 : √3 : 2

These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.

Need help please stressing out over this problem!?!?!

v =  \frac{4}{3} \times \pi \times  {r}^{3}

Finding the radius,

d = 2r, \: r =  \frac{d}{2}  =  \frac{8}{2}  = 4inches

Plugging in our values,

v =  \frac{4}{3}  \times 3.14 \times  {4}^{3}  =  \frac{4}{3}  \times 3.14 \times 64 = 267.95 {inches}^{3}  \\

Rounding to the nearest whol number,

v = 268 {inches}^{3}
