Respuesta :
Area = πr²
π is 3.14. r is the radius of the circle.
If r = 3 then the area is 28.27.
Step by step
- π × 3² | Replace r with your circle's radius
- 3.14... × 9 | Solve groups
- 3.14... × 9 ≈ 28.27
Answer:
A = πr²
Step-by-step explanation:
The formula for the area of a circle is A = πr², where π is approx. 3.14159 and r is the radius of the circle.
