A circle has a radius r which is a positive integer. If the circumference of the circle divided by the area of the circle is a p
1 answer:
The possible value for the radius of the circle is 1 unit
<h3 /><h3>Area and Circumference of a circle </h3>The formula for calculating the area of a circle is expressed as:
- A = πr²
The formula for calculating the circumference is expressed as:
- C = 2πr
where r is the radius of the given circle.
If the circumference of the circle divided by the area of the circle is a prime number, then;
For the value to the prime and r to be an integer, the possible value for the radius of the circle is 1 unit

Answer:
or in decimal form
Step-by-step explanation:
The midpoint of the line with endpoints and
is
. just take the average between the points
so given the points (1,0) and (2,-10)
the midpoint is found as follows:
or in decimal form
To answer this question, you need to draw out the graph first. By doing so, you will be able to know where the other endpoint is located. (Fig. 1)
Next, count the number from the midpoint to the endpoint to determine the coordinates for the other endpoint. (Fig. 2)
Example: From (2, 5) to (6, 3)
x: 2 to 6 = 4 steps
y: 5 to 3 = 2 steps
From there, you can determine the other endpoint like this.
Example: From (2, 5) to the other endpoint
x: 2 to x1 = 4 steps
y: 5 to y1 = 2 steps
Therefore, x1 = -2 and y1 = 7
Other endpoint: (-2, 7)
Sorry for the messy drawing, it is hard to draw without a pen. Haha... hope this helps :)
