Complete Question:

The city of Paris, France is completely contained within an almost circular road that goes around the edge. The radius is 3 miles. Use the map with its scale to estimate the circumference and area of Paris.

(See attachment for map)

Answer:

[tex]C = 18.84\ miles[/tex]

[tex]A = 28.26\ miles^2[/tex]

Step-by-step explanation:

Given

[tex]Radius = 3\ miles[/tex]

Solving (a): Circumference

Circumference (C) is calculated as thus:

[tex]C = 2\pi r[/tex]

Where

[tex]r = radius = 3[/tex]

and

[tex]\pi = 3.14[/tex]

So:

[tex]C = 2 * 3.14 * 3[/tex]

[tex]C = 18.84\ miles[/tex]

Hence, the circumference is about 18.84 miles

Solving (b): Area

Area (A) is calculated as thus:

[tex]A = \pi r^2[/tex]

Where

[tex]r = radius = 3[/tex]

and

[tex]\pi = 3.14[/tex]

[tex]A = 3.14 * 3^2[/tex]

[tex]A = 3.14 * 9[/tex]

[tex]A = 28.26\ miles^2[/tex]

Hence, the area is about 28.26 mi²

Circumference and Area of Paris is 18.84 mile and 28.26 miles²

Given that;

According to map

Radius of Paris = 3 miles

Find:

Circumference of Paris  = 2πr

Area of Paris = πr²

Circumference of Paris in miles = 2(3.14)(3)

Circumference of Paris in miles = 18.84 miles

Area of Paris = πr²

Area of Paris = (3.14)(3)²

Area of Paris = (3.14)(9)

Area of Paris = 28.26 miles²
