It is 78.5 square units.
It is: 25*pi square m
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
A=pi times R squared If the radius is 5, the area is 25pi
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
