An arc of a circle measures 80 degrees and the length of 88pie cm. what is the diameter?

Answers

Answer 1

Answer: If 80° ------> 88π cm
Then 360° ------> x cm

So:

x = (88π x 360) ÷ 80
x = 396 π (lenght of the circle)

The relationship of Lenght of circle and its diameter is:

L = d .π

replacing L:
396 π = d.π ----> d = 396 cm <---- here is your answer

I need help to graphs these problem please

Answers

If you're talking about #5, where you have to graph the equation . . .

All you have to do is find two points on the graph, and draw a line between them.

How do you find points ? That's where you are in control !
Just pick any number you like for 'x', and then use the equation
to calculate the 'y' that goes with it.

Examples:

Pick 'zero' for 'x'.
Y = (1/2)x + 3
Y = 3

Pick 10 for 'x'.
y = (1/2)x + 3
y = 5 + 3
y = 8

Just create two points that way, using the equation. Then mark
the two points on the graph, and draw a line through the two points.
