Answer:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·3.22 = 32.17 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(6.4
2
)2 = 3.14·(3.2)2 = 32.17 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 20.112
4π
= 404.41
(4·3.14)
= 404.41
12.56
= 32.17 square cm(*)
