How do you find the area of a circle with circumference 45?

Answer 1

I found #161# u.a.

The circumference #C# is given by: #C=45=2pir# so that #r=45/(2pi)# The area will be: #A=pir^2# and using our radius we get: #A=pi(45^2/(4pi^2))=2025/(4pi)=161# units of area

To find the area of a circle with a given circumference, you can use the formula: Area = (Circumference)^2 / (4π). So, for a circle with a circumference of 45 units, the area would be: Area = (45)^2 / (4π) = 636.62 square units.
