Answer:

50.27

Step-by-step explanation:

remember that the circumference of a circle is 2πr

so 3.15x8 and then multiply by two

Answer:

200.96 ft²

Step-by-step explanation:

Step 1: Define/formula

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

$a=\pi r^2(3.14*radius*radius)$

Step 2: Solve

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.

$\pi 8^2(3.14*8*8)=200.96ft^2.$

Step 3: Conclude

Therefore, the area of this circle is 200.96 ft.²

You can find the rise by _ the Y-coordinate of the left point from the y-coordinate of the right point

bixtya [17]

Answer:

Subtracting

Step-by-step explanation:

We know that the slope of a line is given by the rise over run. where rise is vertical difference between two points and run is the horizontal distance between the points.

$\text{if }(x_1,y_1) \text{ and }(x_2,y_2)\text{ are two points on a line, then the}\\\text{slope of the line is given by}\\\\\text{Slope, }m=\frac{y_2-y_1}{x_2-x_1}\\\\\text{since slope}=\frac{\text{Rise}}{\text{Run}}, \text{ so Rise}=y_2-y_1\\\\\text{so we can find the rise by subtracting the Y-coordinate of the left point }\\\text{from the y-coordinate of the right point}.$
