Answer:
The equation is:
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.
We used minus (-) because, the amount reduces as the student pays.
Let
So, we have:
Substitute values for Initial and Rate
Express as a function:
Area of circle is 314 inches^2
Circumference of circle is 62.8 inches
Step-by-step explanation:
We need to find area and circumference of the circle whose diameter is 20 inches.
Area of circle
The formula used to find area of circle is:
value of π = 3.14
we know radius = diameter/2
So, radius = 20/2 = 2
Putting value of π and radius we get Area:
So, Area of circle is 314 inches^2
Circumference of Circle
The formula used to find circumference of circle is:
value of π = 3.14
diameter= 20
Putting value of π and diameter we get Circumference:
So, circumference of circle is 62.8 inches
