A den has a circular rug. According to the tag, the rug has an area of 3.14 square meters.
1 answer:
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
