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]
