Question

Find the circumference of circle of radius 7 cm. Also find length of wire required to fence around it two times

Answer 1

Answer:

Circumference = 44 cm, Length of wire required = 88 cm

Step-by-step explanation:

Circumference of a circle = 2πr

                                          = 2×$\frac{22}{7}$×7

                                          = 2×22

                                          = 44 cm

Wire has to be put with 2 rounds ie 2 times the circumference = 2×44

                                                                                                        = 88 cm
