A) From the function p(t)=6(t), we know that p is 6t, so we plug this into it, to get 3.14 * (6t)^2, or 113.04t^2.
B) Using what we got from A), we plug it in and get 113.04 * 8 * 8, or 7234.56 (Use a calculator on this, or just bash it with pencil and paper).
Answer:
0.622
Step-by-step explanation:
According to the question,
62.2% of the respondents from Hawaii said that they had exercised more than 30 minutes a day for 3 days out of the week.

Answer:
$22.75
Step-by-step explanation:
C = $30.25 - ($0.25/min)x, where x is the number of minutes spent on calls
Here, 30 minutes of calls result in this amount of $ left on the card:
C(30) = $30.25 - ($0.25/min)(30 min) = $22.75
Answer:
for every 6 hrs of work you get $1
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
