Question

the circular park of diameter 30m is surrounded by a circular path of width 5m. find its area of path​

Answer 1

$\sf Area \: of \: the \: path = \pi (R² - r²)$

$\sf Here,$

$\sf R = \frac{30 }{2} + 5= 15 + 5 = 20m$

$\sf r = 20 - 5 = 15m$

$\sf Area \: of \: the \: path = \pi (20² - 15²)$

$\sf ⇒ \frac{22}{7} \times 175$

$\sf ⇒550 \: {cm}^{2}$
