find the area and circumference of each circle. Use pi in your answer (example: radius = 8, or diameter = 14).

Respuesta :

Answer:

Solutions below.

Step-by-step explanation:

First, we have to define each of the formulas first.

Area of Circle =

[tex]\pi {r}^{2} [/tex]

Circumference of Circle =

[tex]2\pi \: r[/tex]

With the above formula above, we can find the Area and Circumference for each circle.

Circle A:

Radius = 8

Area =

[tex]\pi {(8)}^{2} = 64\pi {units}^{2} [/tex]

Circumference =

[tex]2\pi(8) = 16\pi \: units[/tex]

Circle B:

Diameter = 14 units

Radius = 14 ÷ 2 = 7 units

Area =

[tex]\pi {(7)}^{2} = 49\pi {units}^{2} [/tex]

Circumference =

[tex]2\pi(7) = 14\pi \: units[/tex]
