Answer:
Circumference of the circular swimming pool = 132m.
SOLUTION
Diameter of the circular swimming pool = 42m.
Radius of the circular swimming pool = 42/2 = 21m.
Circumference of Circle = 2πr (Where 'r' is the radius of the circle).
Here,
r = 21m.
Circumference of the circular swimming pool = 2 × 22 × 3
Circumference of the circular swimming pool = 132m.
PERIMETER OF 3 MOST COMMON SHAPES
1.RECTANGLE
PERIMETER = 2(l+b) , Where l is the length and b is the breadth .
2.Square
PERIMETER = 4a , Where 'a' is the side of the square.
3.Triangle
PERIMETER = a + b +c
To find :-
Given :-
How can we find the αnswer :-
Let's do
Radius = 42/2
Radius = 21 meters
Finding circumference of the circular swimming pool :-
So the circumference of the circular swimming pool is 132m
