1.) R = D÷2 A = πr²
R = 30÷2 A = 3.14 × 15²
R = 15cm A = 3.14 × 225
A = 706.5cm²
Answer: The area of the circle is 706.5cm².
2.) A = πr²
A = 3.14 × 5²
A = 3.14 × 25
A = 78.5m²
Answer: The area of the circle is 78.5m².
3.) R = D÷2 A = πr²
R = 8.6 ÷ 2 A = 3.14 × 4.3²
R = 4.3cm² A = 3.14 × 13.502
A = 42.39628cm²
Answer: The area of the circle is 42.39628cm².
Hope it helps!
