Explanation:

Missing: dm ‎| Must include: dm

Correct me pls if I'm wrong.

1.) 23,223.44 km

2.) 88.2026 m

3.) 16,277.76 dm

4.) 283.385 cm

5.) 12,861.44 mm

Solution:

a.) A= 86 km

= 3.14 (86×86)

= 3.14 × 7,296

= 23,223.44 km

b.) A= 5.3 m

= 3.14 (5.3×5.3)

= 3.14 × 28.09

= 88.2026 m

c.) A= 72 dm

= 3.14 (72×72)

= 3.14 × 5,184

= 16.277.76 dm

d.) A= 9.5 cm

= 3.14 (9.5×9.5)

= 3.14 × 90.25

= 283.385 cm

e.) A= 64 mm

= 3.14 (64×64)

= 3.14 × 4,096

= 12,861.44 mm
