area or circle = πr²
962.5 = 22/7 * r²
6737.5 = 22r²
306.25 = r²
r = 17.5 m
r of path = 17.5 + 3.5 = 21 m
area of pool and path
= πr²
= 22/7 * 21 * 21
= (22 * 441)/7
= 9702/7
= 1386 m²
area of path
= 1386 - 962.5
= 423.5 m²
962.5 = 22/7 * r²
6737.5 = 22r²
306.25 = r²
r = 17.5 m
r of path = 17.5 + 3.5 = 21 m
area of pool and path
= πr²
= 22/7 * 21 * 21
= (22 * 441)/7
= 9702/7
= 1386 m²
area of path
= 1386 - 962.5
= 423.5 m²
