Answer:

19.625 cm² is your answer

Explanation:

Area of the circle can be solved using the equation: Area =
$\pi r^2\\$

Solve for r (radius). To find radius, use Radius =
(diameter)/(2)

Solve for radius

$(5)/(2) = 2.5\\$

Plug in 2.5 for radius. Remember that Area =
$\pi r^2\\$

Area =
$\pi 2.5^2\\$

Simplify

Area =
$\pi 6.25\\$

Area =
$\((3.14)(6.25)\\$

Multiply

Area =
$\ 19.625\\$

19.625 cm² is your answer
