The center of a circle is at the origin. an endpoint of a diameter of the circle is at (-3, -4). how long is the diameter of the circle?

The length of the diameter of the circle is 10 unit.

Step-by-step explanation:

Given : The center of a circle is at the origin. An endpoint of a diameter of the circle is at (-3, -4).

To find : How long is the diameter of the circle?

Solution :

The center of a circle is at the origin i.e.

An endpoint of a diameter of the circle is at

The distance between the center and the end point of the diameter is the radius of the circle.

So, we find the radius with the help of distance formula,

Substitute the value in the formula,

Diameter is twice of radius

Therefore, The length of the diameter of the circle is 10 unit.

the answer is c. hope this !

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
