Solution:

1.) Radius is 2cm

  • A= πr²
  • A= (3.14)(2²)
  • A= 3.14×2×2
  • A= 3.14×4
  • A= 12.56cm²

2.) Diameter is 10c » Radius is 5c

  • A= πr²
  • A= (3.14)(5²)
  • A= 3.14×5×5
  • A= 3.14×10
  • A= 78.5c²

3.) Radius is 6cm

  • A= πr²
  • A= (3.14)(6²)
  • A= 3.14×6×6
  • A= 3.14×36
  • A= 113.04cm²

4.) Radius is 4cm

  • A= πr²
  • A= (3.14)(4²)
  • A= 3.14×4×4
  • A= 3.14×16
  • A= 50.24cm²

Answer:

  • 1.) 12.56cm²
  • 2.) 78.5c²
  • 3.) 113.04cm²
  • 4.) 50.24cm²
