Find the radius and diameter of a frisbee with a circumference of 11 pi inches.

1 answer:

6 0

Circumerence=2pir or dpi were r=radius and d=diameter
11pi=2pir
divid eobt sides by pi
11=2r
dvide 2
5.5=r

11pi=dpi
divide both sides by pi
11=d

diameter=11in
radius=5.5 in

Answer:

1/2

Step-by-step explanation:

remember that the formula for the slope of a line is

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:

Point 1 : (-1,3) and Point 2 : (1,4)

Plug in your values:

$m=\frac{4-3}{1-(-1)}$

$m=\frac{1}{2} \\$

So the slope of this line is 1/2 !
