Step-by-step explanation:

1. r = d/2

= 14m/2

= 7m

A = πr²

= (3.14)(7m)²

= (3.14)(49m²)

= 153.9m²

2. A = πr²

= (3.14)(2m)²

= (3.14)(4m²)

= 12.6m²

3. r = d/2

= 10cm/2

= 5cm

A = πr²

= (3.14)(5cm)²

= (3.14)(25cm²)

= 78.5cm²

4. r = d/2

= 8cm/2

= 4cm

A = πr²

= (3.14)(4cm)²

= (3.14)(16cm²)

= 50.2cm²

5. A = πr²

= (3.14)(5cm)²

= (3.14)(25cm²)

= 78.5cm²
