Answer:
Relation 3 is a function and Relation 4 is nog
The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334

Answer:
35
Step-by-step explanation:
All of the marked angles subtend the same arc, so all have the same measure.
a = b = c = d = 35
b = 35
Answer:
1/2 ÷ 4 = 8
Step-by-step explanation:
Dividing fractions is as easy as pie. Flip the second and multiply.
1/2 ÷ 4 = 1/8
A whole number secretly has a 1 underneath, like this: 4/1
Flip the second number over to get 1/4, then multiply straight across.

= 
Try to do the same for the other answers and see if they're right (they're not).
1/8 x 1/6 = 1/48
1/3 x 1/4 = 1/12
1/9 x 1/2 = 1/18
