Hello!
In this formula, C represents the circumference, as pi and r, the radius are in the equation. 2r is also equal to the diameter.
The answer is the circumference.

Answer: The triangle has two angles of 49.99° and one angle of 80.02°
Step-by-step explanation:
We have a triangle with sides of 7mm, 9mm and 7mm
The triangle has two equal sides, so this means that this is a Isosceles triangle.
The angles are
The base of this triangle is the side with 9mm, and the two base angles are equal.
We can find the base angles by drawing a line from the middle of the base to the top vertice, then we will have a triangle rectangle with a hypotenuse of 7mm, a adjacent cathetus of 4.5 mm, and with this two things we can find the base angle by using the relation
cos(a) = adjacent cathetus/hypotenuse = 4.5mm/7mm
a = Acos(4.5/7) = 49.99°
Then in our isosceles triangle we have two base angles of 49.99°
To find the other angle we can use the fact that the 3 inner angles of a triangle adds up top 180°
Then
49.99° + 49.99° + A = 180°
A = 180° - 2*49.99° = 80.02°
