Arc DC = 27°, so Arc AB = 27° + 54° or 81°.
Answer:
18
Step-by-step explanation:
The circumference of the circular table on Beverly’s porch is 72pi inches. The radius of the table is 18 inches.
In order to solve this, we have to use the formula, 72 pi = 2* r * pi.
r = radius
72pi = circumference
Therefore, the radius of the table is 18 inches.
