Explicación paso a paso:
1. radio= 4 cm
A = πr² = 3.14(4cm)² = 3.14(16cm²) = 50.24cm²
2. diámetro= 14 cm su radio es r = 7.5cm
A = πr² = 3.14(7.5cm)² = 3.14(56.24cm²) = 176.625cm²
3. radio= 15 cm
A = πr² = 3.14(15cm)² = 3.14(225cm²) = 706.5cm²
4. diámetro= 46 cm su radio es r = 23cm
A = πr² = 3.14(23cm)² = 3.14(529cm²) = 1661.06cm²
5. radio= 11 cm
A = πr² = 3.14(11cm)² = 3.14(121cm²) = 379.94cm²
6. diámetro= 50 cm su radio es r = 25cm
A = πr² = 3.14(25cm)² = 3.14(625cm²) = 1962.5cm²
7. radio= 3 cm
A = πr² = 3.14(3cm)² = 3.14(9cm²) = 28.26cm²
8. diámetro= 46 cm su radio es r = 23 cm
