Answer:what is the question
Step-by-step explanation:
Answer:
706.50 mm^2
The formula to find the circumference is 2πr (r : radius)
if the circumference is 30π the the radius is = 15
to find the area we use the following formula :
π*r^2
r = 15 and π is given as 3.14
(3.14)*15^2 = 706.50 mm^2
(-∞, 0) U (8, ∞)
so the smallest angle is angle A which is 30 degree
