Volume = (4/3) * PI * radius^3
80 * PI = (4/3) * PI * radius^3
The 'PI's' cancel out leaving
80 = (4/3) * radius^3
radius^3 = 80/(4/3)
radius^3 = 60

radius = cube root (60)

Ameen went to the salon and had 3/8 of an inch of hair cut off. The next day she went back and asked for another 1/2 of an inch

GaryK [48]

Answer:

Total hair cut off = $\frac{7}{8}$

Step-by-step explanation:

Given - Ameen went to the salon and had $\frac{3}{8}$ of an inch of hair cut off. The next day she went back and asked for another $\frac{1}{2}$ of an inch to be cut off.

To find - How much hair did she have cut off in all?

Proof -

Given that,

Firstly,

She cut off her hair = $\frac{3}{8}$

Then,

She cut off her hair = $\frac{1}{2}$

So,

Total hair cut off = $\frac{3}{8}$ + $\frac{1}{2}$

= $\frac{3 + 4}{8}$ = $\frac{7}{8}$

⇒Total hair cut off = $\frac{7}{8}$
