Answer:
Explanation:
Step 1: Understand the formula for the circumference of a circle
The formula for the circumference of a circle is given by:
C = 2 * π * r
where C is the circumference of the circle, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle. This formula expresses the relationship between the radius and the circumference of a circle.
Step 2: Substitute the radius of the circle for "r" in the formula
Let's say the radius of the circle is "r". Substitute "r" for "r" in the formula for the circumference:
C = 2 * π * r
Step 3: Divide the circumference by the radius
Now that you have the formula for the circumference, divide the circumference by the radius:
C/r = 2 * π
Step 4: Simplify the expression
The expression on the right side of the equation can be simplified to 2 times pi:
C/r = 2 * π
C/r = 2 * 3.14 = 6.28
Step 5: Conclusion
Therefore, it would take 6.28 radii laid end to end to fit exactly around the circumference of the circle.
Note: This answer is only an approximation, as the value of π is an irrational number that cannot be expressed exactly as a fraction or a decimal.
