No, the centroid and Circumcentre are not same but it is same in equilateral triangle.
The intersection of a triangle's perpendicular bisectors is called the circumcenter.A triangle's circumcenter is a location that is equally spaced from each of its vertices.The centroid of a triangle is the location where its medians connect.
Triangle's centroid is always within it. The centroid of a triangle is its center of gravity in physical terms. If the triangle is evenly distributed around the plane's surface and you want to balance it by supporting it at only one point, you must do it near the center of gravity.Are the circumcenter and centroid at the same location? In the case of an equilateral triangle, they will both be.
Therefore, the centroid and Circumcentre are not same but it is same in equilateral triangle.

Okay what’s the question?
Answer:
The answer is 0,66
Step-by-step explanation:
Assuming he gets the exact same shade of green everyday, the ratio of blue to yellow for Marc's green color is 0,66 because 4 / 6 and 6 / 9 give the same results when calculated in decimal.
I hope this answer helps.
Answer:
The reference angle is 
Step-by-step explanation:
The given angle is 
The reference angle is the acute angle, that a given angle makes with the x-axis.
First let us make a sketch of the given angle. <em>See diagram in attachment.</em>
Let 
be the reference angle of
Then, from the diagram, we need to subtract from 
to get to 
.
We can therefore write the following equation and solve for .
We group like terms to get,
We collect LCM to get,
We simplify to get,
We divide through by 
to get,
The correct answer is D.
The area of a circle is given by the formula:
A =
r^2
Since
= 3.14, and r = 6, sub these values into the equation,
A = 3.14 x 6^2
= 113.04
Hope this helped!
