Answer:
Area ≈ 4,500
Step-by-step explanation:
Radius of Circle A
r = √
r = √
r ≈ 12.62
Diameter of Cricle A
d = 2r
d = 2(12.62)
d = 25.24
25.25 x 3 =75.72 --> This is the diameter of Circle B
Radius of Circle B
r =
r =
r = 37.86
Area of Circle B
A =
A = (37.86)²
A = 4,503.09
Ordered pairs on an unit circle..
Exact values of the ordered pairs of the unit circle is represented in pictorial form above in degrees and radians.
Hope this helps.
For simple interest rate,
I=P(i)t
54=900(i)(18/12)
i=54/900*(12/18)=4% annually
