Answer:
9 hours.
Step-by-step explanation:
Let x represent number of hours.
We have been given that Oceanside Bike Rental Shop charges a 18 dollar fixed fee plus 7 dollars an hour for renting bike.
The cost of renting bike for x hours would be .
The total cost of renting bike for x hours would be cost of x hours plus fixed charges that .
We are told that Jason paid 81 dollars to rent a bike. To find the number of hours, we will equate total cost of renting bike for x hours by 81 as:
Let us solve for x.
Therefore, Jason paid for 9 hours to have the bike check out.

Answer:
333 in^3
Step-by-step explanation:
Circumference = pi *d
27 = pi*d
Replacing d with 2*r ( 2 times the radius)
27 = pi * 2 * r
Divide each side by 2
27/2 = pi *r
13.5 = pi *r
Divide by pi
13.5/ pi = r
We want to find the volume of a sphere
V = 4/3 pi * r^3
V = 4/3 pi (13.5/pi)^3
= 4/3 pi * (13.5)^3 / (pi^3)
4/3 pi/pi^3 * (13.5)^3
4/3 * 1/ pi^2 *2460.375
3280.5 / pi^2
Let pi be approximated by 3.14
380.5/(3.14)^2
