Help me please with geometry ​
Yuri [45]

Answer:

Step-by-step explaunfere:

The circumference of a circle is the distance around the outside of the circle. The diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.

1- C ≈ 50.27 in

2- C ≈ 31.42 in

3- A ≈ 201.06

4- A ≈ 314.16

5- C = 14π = 43.982 ≈ 44 inches

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
