Question

29) A gardener wants to fence a circular garden of diameter 14cm. Find the length of the rope required to
fence 4 rounds of the garden. Also, find the cost of rope, if it costs Rs.6 per metre.​

Answer 1

Answer:

176 cm & Rs10.56

Step-by-step explanation:

diameter : 14cm

then radius : 7cm

circumference = 2πr

2 * 22/7 * 7 = 44

then,

if we want 4 rounds of rope then

circumference x 4

44 * 4 = 176

therefore length of rope required = 176cm

cost of rope if per meter cost is Rs 6 per meter

176cm = 1.76 m

then

cost = 6 * 1.76

= Rs10.56
