Answer:
9.42
8.60
4.71
4.39
Step-by-step explanation:
The equation to finding the circumference is πd=C
So for the row with the diameter of 3, you would multiply 3x3.14 to get 9.42
For the next row, you would set up 27=(3.14)d and you would divide the 27 by 3.14 to get 8.60
Next row, multiply 1.5 by 3.14 to get 4.71
Last row, set up the equation 13.8=(3.14)d and divide by 13.8 by 3.14 to get 4.39
Answer:
112
Step-by-step explanation:
Do the opposite to get your answer.
28 x 4 = x
x = 112
You can multiply 3*5*7=105 and any multiple of 105 will have those as prime factors since they will be divisible by them.
