The answer is 78.5 you can get this by multiplying pi by the radius which is 5 then square it and you get 78.5
Answer:
a=78.5 meters^2
Step-by-step explanation:
First, we have to find the radius
r=d/2
r=10/2
r=5
Substitute 5 in for r in the area formula
a=[tex]\pi[/tex]r^2
a=[tex]\pi[/tex]5^2
a=[tex]\pi[/tex]25
Substitute 3.14 in for pi
a=25*3.14
a=78.5 meters^2
Hope this helps!
