PLEASE HELP!!!!!!!!!!!!!!!!!

Answer:
25 π Sq. units
Step-by-step explanation:
We have,
[tex] \boxed{ \mathfrak{ \blue{area \: of \: a \: circle = \pi \times {radius}^{2} } } }[/tex]
and
[tex] \boxed{ \mathfrak{ \blue{radius = \frac{diameter}{2} } } }[/tex]
so using the latter we get,
radius = 10/ 2
radius = 5 units
area = π radius²
area = π (5)²
area = 25 π Sq. units
