Question

John measured the circumference of a circular barrel as 40.6 inches and the diameter is 10 which expression gives an approximate value of pie?

Answer 1

4.06 inches, or about 4 inches.

Explanation:

The value of pi is a circle's circumference divided by its diameter.

Here, the equation is 40.6 ÷ 10.

The quotient of 40.6/10 is 4.06 inches.

I assume the approximate value will be among the range of 4 inches through 4.1 inches.
