There are only 4 radii in a circle.
M is the center of the circle.
Perhaps \( AB=CD \)
Which diagram shows a circle with a point marked in the circle and not on the circle?
Which figure shows the radius of a circle?
Is it possible that the circumference of a circle is 8 meters and its diameter is 4 meters?
There are only 4 radii in a circle.
A radius is a straight line that connects the center of the circle with a point on the circle itself.
Therefore, the answer is incorrect, as there are infinite radii.
False
M is the center of the circle.
Perhaps
CD is a diameter, since it passes through the center of the circle, meaning it is the longest segment in the circle.
AB does not pass through the center of the circle and is not a diameter, therefore it is necessarily shorter.
Therefore:
No
Which diagram shows a circle with a point marked in the circle and not on the circle?
The interpretation of "in a circle" is inside the circle.
In diagrams (a) and (d) the point is on the circle, while in diagram (c) the point is outside of the circle.
Which figure shows the radius of a circle?
It is a straight line connecting the center of the circle to a point located on the circle itself.
Therefore, the diagram that fits the definition is c.
In diagram a, the line does not pass through the center, and in diagram b, it is a diameter.
Is it possible that the circumference of a circle is 8 meters and its diameter is 4 meters?
To calculate, we will use the formula:
Pi is the ratio between the circumference of the circle and the diameter of the circle.
The diameter is equal to 2 radii.
Let's substitute the given data into the formula:
Therefore, this situation is not possible.
Impossible
M is the center of the circle.
In the figure we observe 3 diameters?
Is there sufficient data to determine that
\( GH=AB \)
M is the center of the circle.
Perhaps \( MF=MC \)
In which of the circles is the center of the circle marked?
M is the center of the circle below.
\( AB=10 \)
