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.

5x + 10x = 180
15x = 180
X = 12
5 x 12 = 60
10 x 12 = 120
The angles are 60° and 120°

Answer:
4 11/20
Step-by-step explanation:
Using bidMAs Multiplication comes first before addition
2/5 * 7/6 = 14/30
7/6 * 7/2 = 49/12
Make denominators equal
14/30 * 2 = 28/60
49/12 * 5 = 245/60
Then add
28/60 + 245/60 = 273/60
Finally convert improper into mixed fraction
4 11/20
