Answer:
-99.12525
Step-by-step explanation:
The answer is A. or B. because it states that both the central and inscribed angle have the same endpoints.
Its A,have a nice day! :))))))
Area = PI x r^2
Circumference = 2 x r x PI
Using area find the radius )r)
616 = 22/7 x r^2
Divide both sides by 22/7:
196 = r^2
Take the square root of both sides:
r = 14 cm
Now find the circumference:
2 x 14 x 22/7 = 88 cm
Answer : A) 88 cm
Wall height=wall above ground + wall below ground
or, 6 ft = 4 ft + wall below ground
or, wall below ground = 2 ft
