A wire of length 56 m is bent in the form
of a circle. Find the radius of the circle.
Also find the area. If the same wire is
bent in the form of a square what will be
side and area. Which figure encloses
more area, the circle or the square?
Answers
Answer:
Given:-
- Length of wire = 56m
To find:-
- Radius of circle
- Area of circle
- Side of square
- Area of square
________________________
Since the wire of length 54m is bent in the form of a circle
So, Length of wire = Circumference of circle = 56m
Hence, Circumference of circle = 2πr
56m. = 2πr
radius. = 56×7 / 44 = 8.90mm
So, Area of circle = πr2
= 22/7 × 8.9 = 248.945 m^2
Since the wire of length 54m is bent in the form of a square
So, Length of wire = perimeter of square = 56m
Hence, Perimeter of square= 56m
4×s = 56
s = 56/4 = 14m
So, Area = (side)^2
= (14)^2 = 196m

Since Area of circle is greater than area of square
So, We see that Circle encloses more area than square
Answer:
- Area of circle = 248.95 sq. m
- Area of square = 196 sq. m.
- Circle encloses more area.
Step-by-step explanation:
A wire of length 56 m is bent in the form of a circle.
Means circumference of the circle is 56 m
step 1: Find radius and area of the circle
The circumference of circle =2 × π×r
56 m= 2 × π×r
π×r = 28
r = 28 × 7/22
r = 8.9 cm
Area of circle =
=
Step 2: Side and area of square
If the same wire is bent in the form of a square what will be the side and area.
circumference of circle = perimeter of square = 56 m
4 side = 56
side = 56/4 = 14 m
So, the side square is 14 m
Area of square = side × side = 14 × 14 = 196 sq. m.
Step 3: Compare the area of the circle or the square
Area of circle = 248.95 sq. m
Area of square = 196 sq. m.
So, Circle encloses more area.
