<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:
y=2327.49 ---> 25 hrs.
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327)
Answer:
f(x) = 6
Step-by-step explanation:
