It's B, and being mental won' help when having a calculator next to you) It's B for sure!!!
Are these two separate questions?
Step-by-step explanation:
Answer is 1, because, your multiplying 1 12 times, so it is
1*1*1*1*1*1*1*1*1*1*1*1=1
even if it was 1 to the power of 100, it's still going to be 1, if the base number is 1, then exponent can be any number and still getting 1.
C = 2(pi)r....so we are looking for the radius (r)
42 = 2 * 3.14 * r
42 = 6.28r
42/6.28 = r
6.69 = r <===
