find perimeter and area of shaded region as show in figure
Answers
Answer:
Perimeter = 37.71 cm
Area = 37.71 cm²
mark as brainliest if it helped
Step-by-step explanation:
Dia = 2 * Radius
AD = 12 cm
AB = BC = CD
AB + BC + CD = 12
3AB = 3BC = 3CD = 12
AB = BC = CD = 4 cm
Area of shaded region = top half circle + Bottom half small circle - top half small circle
top half circle radius = 6 cm given
Bottom half small circle radius = AB/2 = 4/2 = 2 cm
top half small circle radius = BC or CD = 4 cm
half circle/semi circle Area = (1/2)π r²
π (pie) = 22/7
Area of shaded region = (1/2)(22/7)(6² + 2² - 4²)
= (1/2)(22/7)(36+4-16)
=(11/7)(24)
=264/7
= 37.71 cm²
Perimeter of shaded Area = top half circle + top half small circle + +Bottom half small circle
Perimeter of half/semi circle = π r
((22/7)(6+4+2)
=(22/7)*12
= 264/7
=37.71 cm

Hi!!!☺☺☺☺
Perimeter = 37.71 cm
Area = 37.71 cm
Dia = 2 * Radius
AD = 12 cm
AB = BC = CD
AB + BC + CD = 12
3AB = 3BC = 3CD = 12
AB = BC = CD = 4 cm
Area of shaded region = top half circle + Bottom half small circle - top half small circle
top half circle radius = 6 cm given
Bottom half small circle radius = AB/2 = 4/2 = 2 cm
top half small circle radius = BC or CD = 4 cm
half circle/semi circle Area = (1/2)π r²
π (pie) = 22/7
Area of shaded region = (1/2)(22/7)(6² + 2² - 4²)
= (1/2)(22/7)(36+4-16)
=(11/7)(24)
=264/7
= 37.71 cm²
Perimeter of shaded Area = top half circle + top half small circle + +Bottom half small circle
Perimeter of half/semi circle = π r
((22/7)(6+4+2)
=(22/7)*12
= 264/7
=37.71 cm
