Answer:

  • It is assumed you need to find the area of shaded region.
  • Results rounded to the nearest hundredth.

#1

Shaded area:

  • A = 32² - 16*π*(32/8)² = 219.75 cm²

#2

Shaded area:

  • A = π*2² - 2*π*(2/2)² = 6.28 cm²

219.75cm²

3.14cm²

Answer:

Solution given:

1.

[r]radius of each circle =32/8=4cm

[l]length of square=32cm

Area of shaded region =area of square- area of 16 circle=l²-11*πr²=32²-16*π*4²=219.75cm²

Step-by-step explanation:

radius for big circle [R]=2cm

radius for small circle [r]=1cm

area of shaded region=area of big semi circle -2 area of semi small circle

=½πR²-2*½πr²

=½*π*2²-π*1²

=2π-π

=π=3.14cm²
