1. What is the circumference of the given circle in terms of pi? radius= 14 in.

A. 14 pi in

B. 28 pi in

C 42 pi in

D 196 pi in

2. What is the circumference in terms of pi? Diameter= 6.6m.
A.16.2 pi m^2
B. 10.89 pi m^2
C. 21.78 pi m^2
D. 43.56 pi m^2

1. B     2. B

Step-by-step explanation:

1. The formula for circumference is C= pi times diameter

Radius is half of diameter, so you'd multiply 14 times 2 which gives you 28. Since it's asking for it in pi, it'll be 28 pi.

2. I think instead of circumference, it's asking for area because if it was asking for circumference the answer would have been 6.6 pi, but that answer isn't there. So if it's asking for area, the formula is A= pi(r²) They gave the diameter instead. Remember, the radius is half of the diameter, so in order to get the radius, you'd divide 6.6 by 2 and get 3.3. Then, multiply 3.3 with the number itself, and you'll get 10.89.

Hope this helps!

the answer is 8/21
