The equation for the area of a circle is: A = πr^2.
A: Area
π: pi
r: radius

To find exact area (we leave pi in the answer): 
- 
Find the radius of the circle. 
The diameter 5ft.
The radius is half the diameter so r = 2.5 ft

-
plug in 2.5 for r in the area equation
A = π(2.5)^2
2.5^2 is 6.25
A = π6.25
A = 6.25π

There you go! The exact area of the circle is 6.25π ft^2

To approximate the area instead of using π in the equation we use (3.14)
So,
A = (3.14)(2.5)^2
A = (3.14)*6.25
Approximated Area = 19.625 ft^2

How can I find list price, selling price, and the discount?
solong [7]

List price is the price which is showcased for users for the purpose of  customers to buy.

List price may be above or below the cost price of the item as per the need of the seller.

Selling price is the price at which an item is sold by the seller. Selling price can be different from list price as there may be discount from the list price.

Selling price above or below cost price is required to find profit or loss on the item.

Discount is the percent deduction on the list price or selling price which is offered to the customer to buy a particular item. Discount is usually less than selling price or list price as it is a depreciation from the actual value.

Disclaimer: No value has been provided for the calculation of the value and hence definition has been given.

What’s the slope and y intercept of all of them
Anestetic [448]

Answer:

See below:

Step-by-step explanation:

Take the difference between y values of any two values and divide by difference in corresponding x values

for example, 1: 66-50/4-1=16

2. 36-30/8-6= 6/2=3

3. 63-56/8-7= 7/1 = 7

4. 100-78/9-7= 22/2 = 11

you can choose any two points, not just the two I used.
