Question

The radius of a circular garden is 56cm Find the length of wire required for 4 rounds of
fencing around the garden​

Answer 1

Before, finding the answer. Let's find out we can find the answer.

• In this question, we are asked to find the length of wire required for fencing around a circular garden.
• So, to find that, we have to find the Circumference of the Circular Garden. For finding the Circumference, we must use the formula of :

$\boxed{ \bf Circumference \: of \: Circle = 2 \pi r }$

• After that, we have to multiply the Circumference with the number of rounds.

__________________________

Given :

• Radius = 56 cm
• Rounds = 4 rounds

To find :

• length of wire required for 4 rounds of  fencing around the garden​

Solution :

Circumference of circular garden = 2πr

                                                        = 2 × 22/7 × 56

                                                        = 112 × 22/7

                                                        = 2464/7

                                                        = 352 cm

4 rounds = 352 × 4

               = 1408 cm

Therefore, the Length required for fencing around the garden is 1408 cm.
