How do you calculate the circumference of a circle if the radius measures 8 inches?

Answer 1

Allison Allen

Circumference of the circle = 50.2655”

Formula for the circumference of a circle is

Circumference #= 2 pi r# where r is the radius of the circle.

Given #r = 8”#

#:.# Circumference # = 2 * pi * 8 = 16 * pi = 50.2655”#

To calculate the circumference of a circle when the radius is given, you can use the formula: Circumference = 2 * π * radius. Plugging in the given radius value of 8 inches into the formula, we get: Circumference = 2 * π * 8 inches. Now, simply multiply 2 by π (approximately 3.14159) and then multiply the result by 8. This gives us the circumference of the circle. Therefore, Circumference = 2 * 3.14159 * 8 inches. Calculating this, we find that the circumference is approximately 50.26548 inches. So, when the radius of the circle measures 8 inches, its circumference is approximately 50.26548 inches.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
