Question

Find the circumference of a circle that has a diameter of 1/6 yard. Use 22/7 for π and reduce the fraction to simplest terms.A) 11/21 yardB) 22/41 yardC) 1/2 yardD) 7/132 yard

Answer 1

Solution

For this case the diameter is :

d= 1/6 yd

And we want to find the circumference so we can use this formula:

$C=2\pi r=2\cdot(\frac{22}{7})\cdot(\frac{1}{12})=\frac{11}{21}yd$

Then the best answer is:

A) 11/21 yard
