djejekfjdnsnansnnn I seen u everywhere .w.
Step-by-step explanation:
to calculate circumference:
if the diameter is 16 then the radius would be 8.
to calculate the area of a circle:
Answer:
m∠3 = 24°
Step-by-step explanation:
By the theorem,
"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."
In the given picture,
∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.
Therefore, m∠3 =
m∠3 =
= 24°
Measure of angle 3 is 24 degrees.
