Question

Chose 2 circles. Find the area of these circles using proper format.

Answer 1

Answer:

Green circle= 4 pi or 12.56.  Blue circle=0.79 or 0.25 pi. Yellow circle= 6.25 pi or 19.63. Orange= 2.25 pi or 7.07.

Step-by-step explanation:

π (Pi) times the Radius squared: A = π r2

or, when you know the Diameter: A = (π/4) × D2

or, when you know the Circumference: A = C2 / 4π

Example: What is the area of a circle with radius of 2 m ?

Radius = r = 2

Area = π r²

 = π × 2²

 = 3.14159... × (2 × 2 )

 = 12.56 m² (to 2 decimal places)

or you can keep it like:

=4 π m²

If you wanted to be exact, you would use pi.

Thank you!!

Correct me if I'm wrong please!
