Circumference of a 20 Inch Diameter Circle.
Step-by-step explanation:
62.832 inches
5′ 2.832″ feet and inches
1.5959 meters
159.59 centimeters
Area of the bottom square part is 10 x 14 = 140 square mm
area of the top rounded part is half a circle
area of a circle = PI x r^2
r = 14/2 = 7
area = 3.14 x 7^2 = 153.86
1/2 circle = 153.86 / 2 = 76.93
total area = 140 + 76.98 = 216.93 square mm
