Answer:
And by definition the radius would be lower than the diameter and we have the following relationship:
And then the best answer would be:
B 2r
Step-by-step explanation:
When we have a circle we know that the area is given by:
And we also know that the diameter is the distance between two any points in the circle passing through the center.
And by definition the radius would be lower than the diameter and we have the following relationship:
And then the best answer would be:
B 2r
Answer:
a.
b.
Step-by-step explanation:
a. The sides of an Equilateral triangle are all equal.
Then, in this case:
Based on this, you can identify that AD divides the side BC into two equal parts and the triangle into two equal Right triangles. Then:
Knowing the length CD, you can find "x" using the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs.
In this case:
Substituting values and solving for "x", you get:
b. By definition, the measure of each interior angle of an Equilateral triangle is 60 degrees. Therefore:
