Question

if a wire is 250 rs per metre and 3 rounds are to be fenced with it for a ground having 77 m of circumference what will be the cost of wire in total​

Answer 1

Answer:

For inside distance :

Radius = 70 m

Circumference = 2πr = 440 m

For outside distance :

Radius = 70+7=77 m

Circumference = 2πr = 484 m

Total length = 440+484=924 m

Cost = Rs.7×924=Rs.6468ㄔㄨㄎㄔㄜㄍ

Answer 2

Answer:

The total cost of the wire will be ₹57750.

Step-by-step explanation:

Here in this question, we have been asked to find the total cost of the wire required to fence 3 rounds of a ground having 77m circumference.

For finding the cost of the wire required we need to first find the length of wire required:

⇒77×3 m

⇒231 m

As we got the length of wire required so we will just multiply it by the cost per meter as shown below:

⇒₹250×231

⇒₹57750 m

Hence the total cost of wire required to fence the garden 3 times is ₹57750
