Answer:
Step-by-step explanation:
#1. You need to find the perimeter or circumference of the circular pool
the formula is:
c = 2π r
where r = d/2
so r = 3/2 = 1.5
so c = 2π r = 2π(1.5) = 3π = 9.42m
#2. get circumference of the 2 circles, using same formula
c = 2π r
where r = d/2
c of big = 2π (12/2) = 12π
c of small = 2π (5) = 10π
so difference of Big and Small = 12π - 10π = 2π = 6.28m
