C) 8:32 is equal is equivalent to 4/16
Answer:
B = 25
Step-by-step explanation:
x/100×8.5=2.1
8.5x/100=2.1
8.5x=100×2.1
8.5x=210
8.5x/8.5=210/8.5
x=24.70
x=25
Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>
