The measure of angle ACB for circle centered at point O is 21°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
∠AOB = 2 * ∠ACB (angle at center is twice the angle at circumference)
42 = 2 * ∠ACB
∠ACB = 21°

Answer:
Step-by-step explanation:
Here, d=12 m
r=12/2=6 m
Now,
Circumference(c)=2πr
=2π6
=12π m
