Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
= 2π × 18 × 
= 36π ×
( cancel 36 and 24 by 12 )
= 3π × 
=
→ C
The radius of B is 2.5cm.
<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
