Question

There is 3m wide path around a circular cricket ground having the diameter if 137m. Find the area of the path.

Answer 1

Answer:

area of path =18.84m

Step-by-step explanation:

Given : diameter of circular path= 137m

path around cricket ground = 3m

Solution : radius of a circular path= 137/2

= 68.5 m

radius of ground with path=68.5+3=71.5m

$area \: of \: circular \: path = 2\pi \times r$

$= 2 \times 3.14 \times 68.5$

$= 430.18m$

$area \: of \: ground \: along \: with \\ \: path = 2\pi \: r$

$= 2 \times 3.14 \times 71.5$

$= 449.02m$

$area \: of \: path \: = area \: of \: \\ cricket \: ground \: along \: with \: \\ path \: - area \: of \: cricket \: \\ ground$

$= 449.02 - 430.18$

$= 18.84m$
