Step-by-step explanation:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·0.52 = 0.78 square units(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(1
2
)2 = 3.14·(0.5)2 = 0.78 square units(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 3.142
4π
= 9.86
(4·3.14)
= 9.86
12.56
= 0.78 square units(*)
