To find the length of the rope needed to fence a circular garden, we need to calculate the circumference of the circle. The circumference of a circle is given by the formula C = πd, where C is the circumference and d is the diameter of the circle.
Given that the diameter of the circular garden is 21m, we can substitute this value into the formula to find the circumference.
C = πd
C = π(21m)
C = 22/7 * 21m
C ≈ 66m
So, the length of the rope needed to fence the garden once is approximately 66 meters.
Since the gardener wants to make 2 rounds of fence, we need to multiply the length of the rope needed for one round by 2.
Length of rope needed for 2 rounds = 66m * 2 = 132m
Therefore, the gardener needs to purchase a rope of length 132 meters.
To find the cost of the rope, we need to multiply the length of the rope by the cost per meter, which is given as rupees 4.
Cost of the rope = Length of rope * Cost per meter
Cost of the rope = 132m * 4
Cost of the rope = 528 rupees
Therefore, the cost of the rope the gardener needs to purchase is 528 rupees.
In summary:
- The length of the rope needed to fence a circular garden of diameter 21m is 66 meters.
- If the gardener wants to make 2 rounds of fence, he needs to purchase a rope of length 132 meters.
- The cost of the rope, considering it costs rupees 4 per meter, is 528 rupees.
Given that the diameter of the circular garden is 21m, we can substitute this value into the formula to find the circumference.
C = πd
C = π(21m)
C = 22/7 * 21m
C ≈ 66m
So, the length of the rope needed to fence the garden once is approximately 66 meters.
Since the gardener wants to make 2 rounds of fence, we need to multiply the length of the rope needed for one round by 2.
Length of rope needed for 2 rounds = 66m * 2 = 132m
Therefore, the gardener needs to purchase a rope of length 132 meters.
To find the cost of the rope, we need to multiply the length of the rope by the cost per meter, which is given as rupees 4.
Cost of the rope = Length of rope * Cost per meter
Cost of the rope = 132m * 4
Cost of the rope = 528 rupees
Therefore, the cost of the rope the gardener needs to purchase is 528 rupees.
In summary:
- The length of the rope needed to fence a circular garden of diameter 21m is 66 meters.
- If the gardener wants to make 2 rounds of fence, he needs to purchase a rope of length 132 meters.
- The cost of the rope, considering it costs rupees 4 per meter, is 528 rupees.
