The equation of a circle with center at point (h, k) and radius of r units is given by
From the diagram, the center of the given circle is at points (-2, 1) and the radius is 3 units.
Therefore, the equation of the given by
The second sentence “ stella ate 3 times as many cherries as adam” it shows that stella ate 6 cherries.
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
( r is the radius )
given arc = 63.48π , then
2πr × = 63.48π ( cancel 2π on numerator/ denominator )
r × 
π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
