Question

A circular plot has a radius of 4.2 m. If three rounds of wire are fenced
around it, what will be the length of the wire? Express your answer in
hm

Answer 1

circumference of plot =2πr

=. 2×22/7 ×4.2

2×22×0.6

44 × 0.6

26.4m

now the wire is fenced 3 rounds. so,

total length of wire = 3 ×26.4 =. 79.2 m

hope it helps

Answer 2

Step-by-step explanation:

radius of circular plot = 4.2 m

circumference =

$2\pi r$

2×22×4.2

7

2×22×0.6= 26.4 m

by question there has been 3 rounds of wire

so, 3×26.4= 79.2
