Find the area of circle whose diameter is 8 m.
Choices.
A) 50.00 square meter  B) 50.04 square meter  C) 50.28 square meter  D) 50.24 square meter  E) 50.43 square meter

Rationale: 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
Answer: C
