The figure below shows the circle inside of a square if the radius of the circle is 8cm find the following by showing the formulas of the work
a. the circumference of the circle ?

b. the area of the circle

c. the area of the square

A. The circumference of the circle:
C = 2 π r = 2 * 3.14 * 8 = 50.24 cm

B. The area of the circle:
A = π r² = 3.14 * 8² = 200.96 cm²

C. The area of the square:
Let's calculate first the side of the square. It is equal to 2r = 2*8=16 cm

The area of the square is:
16*16 = 256 cm²

Hope that helps.
