Answer:
or
Step-by-step explanation:
To find the circumference, you must first find either the diameter or the radius.
To find the diameter, you can multiply the radius twice.
To find the radius, you can divide the diameter by 2.
Once you have the diameter, you then multiply it by pi, also known as 3.14.
OR
Once you have the radius, you them multiply it by pi, also known as 3.14, and then multiply your product by 2.
Answer:
Step-by-step explanation:
Mark got 54 out of 66 correct in his test.
We need to find what fraction of the marks did he get correct,
Total number of questions = 66
Total number of correct answers = 54
The answer is B. centroid, which is the intersection of three medians of the triangle's sides.
Let's look into other answers as well:
A. Circumcenter
It is the point where three perpendicular bisector meet, and is not correct as we can see there is no indication of right angles.
The first photo is what a circumcenter looks like:
C. Incenter
It is the point where the angle bisectors of the triangles meet, which is not indicated in the photo as well.
The second photo is what a incenter looks like:
D. Orthocenter
It is a point where the altitudes of a triangle intersect, and is not indicated by the figure.
The second photo is what a Orthocenter looks like:
Therefore the answer is B. Centroid.
Hope it helps!
