Answer: OPTION A
Step-by-step explanation:
Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:
The equation of the circle is standard form is:
Where r is the radius and (h,k) is the point of the center of the circle.
As we know the diameter, we can find the radius:
Substitute it into the equation:
Then, the answer is:
Answer:
756 cookeys
Step-by-step explanation:
Answer:
For question 5 the correct formula is C=πd
For question 6 the correct formula is C=2πr
For question 7 the answer is 56.52 I think I'm not 100% sure though
For question 8 the answer is 31.4
Step-by-step explanation:
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : Two triangles are congruent if "ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle."
