Answer:
i don't know how to solve the first one but the second one is 3
The formula for the area of a circle is r² x π.
-Since we know the diameter of the circle, we can divide by 2 to find the radius of the circle.
10/2 = 5
-From here, we can substitute our values in. Since we're using 3.14 for pi, we'll substitute that as well.
(5)² x (3.14)
-And finally, we can solve to find the area of the circle.
(25) x (3.14)
(78.5)
Therefore, the answer is 78.5 meters.
