I believe it is A because a diameter is the line that starts at one end of the circle and ends at the other end.

Answer 3

Oh Ok Thank You :) Can You Help With Another
If a circle has a radius of 18 cm, what is the diameter of the circle?

Answer 4

the radius is half of the diameter, therefore all you have to do is multiply the radius by two in order to find the answer which is 36.

Answer 5

diameter always passes through the center.

Answer 6

Thanks You Which statement is true about the circumference of a circle?
A. it is about 3 times the radius.
B. It is about 3 times the diameter.
C. It is about twice the radius.
D. It is about half the diameter
Would This One Be D?

Answer 7

no
the formula is 3.14 (pi) times the diameter

the answer is B

Answer 8

The word about the the key word if you know the formula

Answer 9

What is the approximate circumference of a circular saw blade with a radius of 10.4 inches? (Use π = 3.14)
A. 97.968 inches
B. 16.328 inches
C. 32.656 inches
D. 65.312 inches

Answer 10

D because radiusx2=diameter and diameterx3.14=circumference

Answer 12

Yeah sure. Have you tried to work them out yet?

Answer 13

Yeah But I Think They Are Really Hard. Like I Don't Know How To Solve Them >.<
