Answer:
28.2743 square feet (28 square feet, rounded)
Step-by-step explanation:
The area of a circle is given by the equation
Area = πr^2
Plug in 3 for the radius
Area= π(3)^2
3 squared is 9
Area= 9 π
Area= 28.2743 square feet
Rounded to the nearest square foot, the area of the circle is 28 square feet.

Answer:
3600
Step-by-step explanation:
4.8x10^3-1200=3600
Answer: y=3/2x
Step-by-step explanation:
First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.
An equation in slope intercept form is as follows:
y=mx+b
To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.
We can use the slope formula,
, to find the slope, m.
= 
Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.
