Question

A gardener wants to fence a circular garden of diameter 21m. Find the
length of the rope he needs to purchase, if he makes 2 rounds of fence.
Also find the cost of the rope, if it costs ₹ 4 per meter.

Answer 1

d =21 then

r=21/2

length of rope for one round = 2pie r

2×22/7×21/2 = 22×3 =66 m

fir two rounds

132m

cost =132×4 = ₹528

hope this will help you

Answer 2

Answer:

131.94m and £527.76

Step-by-step explanation:

Circumference = π x Diameter

Circumference = π x 21m

Circumference = 65.97

65.97m = 1 round of fence

2 rounds of fence = 65.97 x 2 = 131.94m

131.94m x £ 4 per meter = £527.76
