Answer:

Diameter = 2 m

Radius = 1 m

Area = 3.14 m²

Circumference = 6.28 m

Step-by-step explanation:

✔️Area of the circular rug is already given as 3.14 m²

✔️find radius (r):

Area = πr²

Thus,

Take π as 3.14

3.14*r² = 3.14

Divide both sides by 3.14

r² = 3.14/3.14

r² = 1

find the square root of both sides

r = √1

radius (r) = 1 m

✔️Diameter = 2*r = 2*1 = 2 m

✔️ Circumference = 2πr

r = 1 m

π = 3.14

Thus,

Circumference = 2*3.14*1 = 6.28 m
