Answer:
Radius: 8
Circumference: 50.27
πr^2 = Area of circle
201.06 = πr^2
divide by pi
201.06 / π = 63.9993857161 = 64
64 = r^2
Square root both sides to get radius.
= 8
r = 8
Circumference = π x diameter
Diameter = 2 x radius
Circumference = π x 16 = 50.2654824574 = 50.27
Answer:
51
Step-by-step explanation:
28 + 23 = 51
You want to compute the total area of the figure. The figure is composed by four 6x4 rectangles, and two 4x4 squares.
The area of one rectangle is 
The area of one square is 
You have four rectangles and two squares, so the answer is

Simplifying the exponents will help you multiply, then subtract, and then the equation is easy to solve
