Sam = 32 years
Step-by-step explanation:
Oooh fun!
Alright,
formula for a sphere is (4

r^3)3
4*pi*6^3=2714.34/3
904.78
Now you can do this 2 ways. First is that a cone is 1/3 of a sphere with the same radius so just take 904.78 and multiply it by 1/3 and then by 2 to get 2/3 of it or do this.
cone~ (6^2*pi*10)/3
376.99
and subtract
<span>904.78-376.99=527.79
</span>
<span>527.79^3 greater. Check my math. I could be wrong.</span>
To solve part a, do the following.
49.84-44.50=<span>5.34
5.34/44.50=x/100
after solving the proportion, x would be equal to 12.
To solve part b, do the following.
50+12=62
</span>To solve part c, do the following.
The amount of the tip is:
x/<span>57.50=62/100
which is </span><span>35.65
The total bill is:
35.65+</span>57.50=<span>93.15</span>
I belive the answer to be b
