Formula for finding circumference of a circle is 2πr.

Step-by-step explanation:

The given question says what is the circumference of a circle that is 9cm.
As radius is required for finding circumference of a circle, the formula is 2πr.
Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR

If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
So the circumference of the given circle would be 18π or 56.52 cms.

How can you find the number of inches in one mile

tamaranim1 [39]

You convert it to feet. There are 5,280 feet in a mile. Then convert it to inches. 5,280 feet multiplied by 12 (since there are 12 inches in a foot) is 63,360.

So... 1 mile= 5,280 feet
5,280 feet= 63,360 inches
and so
1 mile= 63,360 inches
