Answer:
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!

Answer:
864 sq. in.
Step-by-step explanation:
The figure is a cube
The surface area of a cube is equal to
S= 6b^2
where
b is the length side of the cube
In this problem we have
b=12 in.
substitute
S=6(12)^2 = 864 sq. in.
