Answer:

Solutions below.

Explanation:

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

Area of Circle =

$\pi {r}^(2)$

Circumference of Circle =

$2\pi \: r$

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

Circle A:

Radius = 8

Area =

$\pi {(8)}^(2) = 64\pi {units}^(2)$

Circumference =

$2\pi(8) = 16\pi \: units$

Circle B:

Diameter = 14 units

Radius = 14 ÷ 2 = 7 units

Area =

$\pi {(7)}^(2) = 49\pi {units}^(2)$

Circumference =

$2\pi(7) = 14\pi \: units$
