The area of a circle is 132.7 square cm. Find the diameter.
2 answers:
Answer:
13
Step-by-step explanation:
To find the diameter, use the diameter formula.
d = 2r (r = radius)
In this case, we don't have a radius so to find the radius, use the radius formula.
r = (A = area)
So, r = square root of 132.7/pi
r is approximately 6.5
Now we have the radius so we can find the diameter:
d = 2(6.5)
d = 13
Diameter is 13

Answer:
Students ticket = $4
Child ticket = $1
Adult ticket = $5
Step-by-step explanation:
Let the price of the student ticket be $x and the price of a child ticket be $y. An adult ticket costs as much as the combined cost of a student ticket and a child ticket, so the price of one adult ticket is $(x+y).
1. A movie theater advertises that a family of two adults, one student, and one child between the ages of 3 and 8 can attend a movie for $15. Then
2. If you purchase 1 adult ticket, 4 student tickets, and 2 child tickets for $23, then
Now, solve the system of two equations:
Solve the last equation
Students ticket = $4
Child ticket = $1
Adult ticket = $5
