find the area of circle whose diameter is 8 m .
diameter = 8 meter . radius = diameter / 2 . = 8 / 2 . = 4 meter . area of a circle = ï € r 2 . here , pi ( ï € ) = 3.14 meter , radius ( r ) = 4 . area of a circle = 3.14 ã — 4 ã — 4 . . = 3.14 ã — 16 . = 50.28 square meter answer : c
circle_area(divide(8, const_2))
