area: 221.5584 square units

area: 78.5 square units

area: 452.16 square units

area: 36.2984 square units

area: 314 square units

area: 886.2336 square units

radius: 12 units

diameter: 16.8 units

radius: 3.4 units

diameter: 10 units

Please use the exact numbers. >w

Answer 1

Radius 12-->452.16

Diameter 16.8-->221.5584

Radius 3.4-->36.2984

Diameter 10-->78.5

Explanation:

Answer 2

Radius: 12 units

• Area: πr² = 3.14*12² = 452.16 square units

Diameter: 16.8 units

• Area: πd²/4 = 3.14*16.8²/4 = 221.5584 square units

Radius: 3.4 units

• Area: πr² = 3.14*3.4² = 452.16 square units

Diameter: 10 units

• Area: πd²/4 = 3.14*10²/4 = 78.5 square units
