Given:

The diameter of the circle = d = 14 cm

The radius of the circle = r = d/2 = 7 cm

The circumference is given by the formula: 2πr

so, the exact value = 2π * 7 = 14π cm

The approximated value to the nearest hundredth = 43.98 cm

The area of the circle is given by the formula: πr²

The exact value of the area = π * 7² = 49π cm²

The approximated value to the nearest hundredth = 153.94 cm²
