How do i measure the diameter of a circle?

Answer:

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

there’s 2 basic cases you’ll see to find the diameter (a line that basically cuts the circle in half)

you’ll either be given the radius (the distance between the center of the circle to any point on the circle) or the circumference (the perimeter of the circle)

so you have two equations:

diameter= 2*radius

circumference= diameter * pi

if they gave you the radius, simply multiply by 2 as the first equation states. if they give you the circumference, divide the circumference by pi (which is approx. 3.14)

A cafeteria worker is wondering how student lunch prices at a high school have changed over time. She researches lunch prices for the years 2000 through 2015 and plots the data in a scatter plot. The best-fit line for the data has the equation y = 0.057x + 1.150, where x is the number of years since 2000 and y is the student lunch price, in dollars.

Determine whether each statement below is true or false based on the equation of the line of best fit. Select True or False for each statement:

The student lunch price was generally increasing between 2000 and 2015

The student lunch price changed by approximately 5.7 cents per year.

The student lunch price in 2015 was approximately $1.15​

A new seven – story apartment building is opening in our town. I was curious when I read the apartments on the higher floors were more expensive, so I went to the open house.

I discovered that there is only one very large apartment on the top floor. Each floor has twice as many apartments as the floor above it. The lowest floor contains only one-room studio apartments which are very small.

How many apartments are in this new building?

Find the generalized formula that would tell me how many apartments would be in this building if it had “X” stories?
