thanx so much

What are the diameter and radius of a circle with a circumference of 28π m?









A.

d = 28 m
r = 14 m








B.

d = 14 m
r = 28 m








C.

d = 14 m
r = 7 m








D.

d = 7 m
r = 14 m

Answer 7

circumference is 28pi?

Answer 8

yes would it be A?

Answer 9

that is correct cause 28 is 2r
and r=d/2=14

Answer 10

thanx Which is the best approximation for the circumference of a circular fish pond that is 24 ft in diameter?

38 ft







B.
72 ft







C.
75 ft







D.
150 ft

Answer 11

would this 1 be c?

Answer 12

C=2pi*r
d=2r

Answer 13

d=24 given, so multiply d*pi=75.40 which is close to 75 ft

Answer 14
