It's very simple! You just need to square the given value of radius (r) and then multiply it by pi (π) to get the area of a circle!
A = πr²
Take note as well that the unit symbol must be in square units (such as m², cm², etc.).
1. 4 cm
A = π(4)²
A = π(16)
A ≈ 50.2654824574
A ≈ 50.27 cm²
2. 12 in
A = π(12)²
A = π(144)
A ≈ 452.389342117
A = 452.39 in²
3. 7 cm
A = π(7)²
A = π(49)
A ≈ 153.938040026
A = 153.94 cm²
4. 15 cm
A = π(15)²
A = π(225)
A ≈ 706.858347058
A = 706.86 cm²
5. 6 cm
A = π(6)²
A = π(36)
A ≈ 113.097335529
A = 113.1 cm²
