Which pair of numbers has a GCF of 3? (A) 1 and 6 (B) 2 and 3 (C) 2 and 6 (D) 3 and 4

None of the above

Step-by-step explanation:

To find the GCF of something find the prime factorization of each number, then see which numbers are the same. After that multiply the numbers that are the same.

(PF): Prime Factorization

A: PF - 1   PF - 2 · 3 (Since they don't have any numbers in common the GCF is 1)

B: PF - 2  PF - 3 (The GCF is also 1)

C: PF - 2  PF - 2 · 3 (Because they have 2 in common the GCF is 2)

D: PF - 3  PF - 2 & 2 (The GCF is 1)

None of the options have a GCF of 3. Therefore it is none of the above

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

step-by-step explanation:

mean or average is 40.6
