Cameron drew a circle for a craft project. The circumference of the circle was about 47.1 inches, and the diameter of the circle was 15 inches. Which expression best represents the value of p?

Answer :

Answer : The expression best represents the value of p is, [tex]\pi=\frac{47.1\times 2}{2\times 15}[/tex]

Step-by-step explanation :

Given:

Circumference of circle = 47.1 inches

Diameter of circle = 15 inches

First we have to calculate the radius of circle.

[tex]\text{Radius of circle}=frac{\text{Diameter of circle}}{2}[/tex]

[tex]\text{Radius of circle}=frac{15}{2}inches[/tex]

Now we have to calculate the value of p or π.

Circumference of circle = [tex]2\pi r[/tex]

where,

r = radius of circle

Circumference of circle = [tex]2\pi r[/tex] = 47.1 inches

[tex]2\pi r[/tex] = 47.1 inches

[tex]\pi=\frac{47.1}{2\times (\frac{15}{2})}[/tex]

[tex]\pi=\frac{47.1\times 2}{2\times 15}[/tex]

[tex]\pi=3.14[/tex]

Thus, the expression best represents the value of p is, [tex]\pi=\frac{47.1\times 2}{2\times 15}[/tex]
