A circle has a radius of 8. Find the area of a sector of this circle that is intercepted by central angle measuring pi over 7

Mathematics

Savatey [412]3 years ago

Answer:

14.4 square units

Step-by-step explanation:

Keep in mind that the area here is a fraction of the area of a full circle of radius 8.

(area of sector) = (fraction)(pi)(8)^2

The fraction is the given central angle (pi over 7) divided by 2pi:

       pi            1

   --------- * ----------- = 1/14

     7             2pi

Multiply the formula     (fraction)(pi)(8)^2     found above by this fraction:

area of sector = (1/14)(pi)(8)^2  =  14.4 square units

Meat costs $8.00 per pound at a store. What is the slope?
-BARSIC- [3]

Answer:

The slope is 8.

Step-by-step explanation:

If you were to graph the price of meat per pound, you would need to choose the x-axis and y-axis labels.

The x-axis is the <u>independent</u> variable, meat in pounds.

The y-axis is the <u>dependent</u> variable, price in dollars.

The price depends on the number of pounds you buy.

Slope is calculated using rise over run, or:

m = \frac{rise}{run}

"Rise" is the number of squares going up.

"Run" is the number of squares going to the right.

In the graph below, <u>to go from one red dot to the next, you count 1 to the right and 8 going up</u>.

m = \frac{rise}{run}

m = \frac{8}{1}

m=8

Therefore, the slope is 8.
