Answer:

The area of a circle with radius 0.2865 is 0.2579

Explanation:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·0.292 = 0.26 square meters(*)

Area of a circle in terms of diameter:

Area = π·(d2)2 = 3.14·(0.572)2 = 3.14·(0.29)2 = 0.26 square meters(*)

Area of a circle in terms of circumference:

Area = C2

= 1.82

= 3.24

(4·3.14)

= 3.24

12.56

= 0.26 square meters(*)
