Answer:
The area of a circle with radius 0.2865 is 0.2579
Step-by-step 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
4π
= 1.82
4π
= 3.24
(4·3.14)
= 3.24
12.56
= 0.26 square meters(*)

y + 6 - 6 = 10 - 6
y = 10 - 6
y = 4
