Find the circumference of each circle

Question 1

Question 2

Answer:

$\large\boxed{\mathtt{C=100 \pi \ in.}}$

$\large\boxed{\mathtt{C \approx314.16 \ in.}}$

Explanation:

$\textsf{We are asked for the circumference of this circle.}$

$\textsf{Let's review what the Circumference of a circle actually is.}$

$\large\underline{\textsf{What is the Circumference?}}$

$\textsf{The Circumference is is the length 'on' the circle.}$

$\textsf{Circumference is the Perimeter of the Circle; The sum of all the curved edges.}$

$\large\underline{\textsf{How do we find the Circumference?}}$

$\textsf{To find the Circumference, we should use a common, and simple formula.}$

$\mathtt{Circumference=(Diameter) \pi}$

$\textsf{Pi will be multiplied by the Diameter of the Circle.}$

$\textsf{Because we are given the Diameter, we can start solving for x.}$

$\large\underline{\textsf{Substitute;}}$

$\mathtt{Circumference \ (C)=(100 \ in.) \pi}$

$\large\boxed{\mathtt{C=100 \pi \ in.}}$

$\large\boxed{\mathtt{C \approx314.16 \ in.}}$
