Area of Shaded

Find the area of the shaded area shown.

Solution:

  • A = s²
  • A = 32cm
  • A = 32cm x 32cm
  • A = 1024
  • A = 32/4/2
  • A = 32 ÷ 2
  • A = 8
  • A = 8 ÷ 2
  • A = 4

So in the inscribed circle there are 16.

  • A = 16 radius ²
  • A = 16 x 4r²
  • A = 4 x 4
  • A = 16
  • A = 16π x 16
  • A = 256π
  • A = 256 x 3.14
  • A = 803.84
  • A = 1024cm - 803.84
  • A = 220.16cm²
