Swimming half way around implies half of the circumference.
Circumference = pi x diameter
C = pi x 20
C = 20pi
20pi / 2 = 10pi
You swam 10pi meters = 31.42 meters.
Hope this helps!! :)
The area of the blue glass that will be needed to fill each butterfly dot is 144π.
<h3>How to calculate the area?</h3>
Fron the information given, the artist is creating a large butterfly sculpture outside a museum and there is a circular dot on each wing made out of a metal ring.
The radius is given as:
= 24π/2π
= 12
Therefore, the area of the blue glass will be:
= π12²
= 144π
