First we will change them on the same denominator which will be 12. If we do something to the denominator we must do the same to the numerator so :
For 1/3 we get 4/12 because (1/3)*4 = 4/12
And for 2/3 we get 8/12 because (2/3)*4 = 8/12
So 1/3 is the smaller fraction, 7/12 is in the middle and 2/3 is the bigger fraction.
75.4
12 would be considered the radius
C = 2 pi R
so just insert that into the formula and the answer should be
75.39 but if you round up it would be 75.4
Answer:
20xπ units
Step-by-step explanation:
Use the formula for the length of an arc.
θ/360 × 2πr
The length of the arc and the central angle is already given.
18/360 × 2πr = xπ
Solve for r.
r = (xπ)/(18/360)/(2π)
r = 10x
The radius is 10x.
The circumference is 2πr.
2π(10x)
20xπ
The circumference of the circle is 20xπ units.
Answer: D
Step-by-step explanation:
Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2. So 1/2 of 60 is 30
