Answer:
1)
Area
2)
1/2
3)
Radius
Step-by-step explanation:
We know that for any circle with radius r the formula for the area and circumference of the circle is given as:
Area of circle=πr².
and circumference of circle = 2πr.
Hence, to describe the relationship between the area of a circle and its circumference.
The Area of circle is 1/2 times the radius times the circumference.
( Since,
Area=1/2 × r× 2πr
Area=πr² )
Answer:
This means that, when the price of a book from a publisher is $60, the bookstore will sell it for $88 to the students.
Answer: The mean is 27.
Step-by-step explanation: You add up all of the numbers and divide the sum by the amount of numbers you have.

move the 3 and add it to 13 and get 16
4x=16
now divide 16 by 4
x=4
