<h3>What is a circle?</h3>A circle is the locus of points equidistant from a common point which is called the center of the circle.
Analysis:
Area of circle A = π/4 = π
/4 = 225π/4
Area of circle B = π
But A = 9B
225π/4 = 9 x π
= 225/36 = 25/4
r = = 5/2 = 2.5cm

Answer: The radius of circle is 19.1 meters.
Explanation:
Since we have given that
Circumference of a circle = 120 meters
As we know the formula for "Circumference of circle" i.e.
Hence, the radius of circle is 19.1 meters.
Answer:
- 2.54 km
Step-by-step explanation:
<em>See the attached</em>
All given details are reflected in the diagram (not to scale)
- PA is at 225°, PB is at 116°, BA is at 258°
- AB = 3.9 km
- AP = x
- m∠P = 225° - 116° = 109°
- m∠A = 258° - 225° = 33°
- m∠B = 180° - (109° + 33°) = 38°
<u>Use the law of sines:</u>
- x/ sin 38° = 3.9 / sin 109°
- x = 3.9 sin 38° / sin 109°
- x = 2.54 km (rounded)
