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.

Answer:
<h2>The answer is B. y=3/5x+1</h2>
Answer:
C. 38°
D. 30°
Step-by-step explanation:
The relevant relation in both cases is the inscribed angle measures half the measure of the arc it intercepts.
__
C. Angle TSQ intercepts arc TQ, so the measure of arc TQ is 2(86.5°) = 173°. The measure of arc TR is the difference between the measures of arcs TQ and RQ, so is ...
arc TR = 173° -135° = 38°
__
D. Inscribed angle PQR intercepts arc PR, so is half its measure.
angle PQR = 60°/2 = 30°
120 is the answer because your find the area
