Answer:
Area = 6.6 cm²
Step-by-step explanation:
Area of the shaded region =
Area of Rectangle - Area of Trapezoid - Area of circle - Area of Triangle
Area of rectangle = Length x Breadth
= 3 x ( 1.5 + 2 + 1.5)
= 3 x 5
= 15 cm²
Area of the trapezoid = h x ( a + b )/2
= 1.5 x ( 3 + 1)/2
= 1.5 x 2
= 3 cm²
Area of the circle = π x r²
= 3.14 x 1 [diameter, d = 2 cm, r = d/2 =1]
= 3.14 cm²
Area of triangle = (1/2) x base x height
= (1/2) x 3 x 1.5
= 2.25 cm²
Area of the shaded region = 15 - 3 - 3.14 - 2.25
= 6.61 cm²
= 6.6 cm ² [ round to nearest tenth ]
Answer:
1. 45.76, 52.17, 54.2, 55.16, 56.78
2. 9.18, 9.2, 9.98, 10.54, 11.23
3. 0.01, 0.05, 0.067, 0.07, 0.09
4. 33.14, 33.15, 33.45, 33.52, 33.55
5. 3.45, 4.45, 4.9, 5.49, 6.5
2x+4(2x+7)+3(2x+4)
2x+8x+28+6x+12
16x+40
16x+40 would be the answer you can’t solve it any further
Answer:
x = 35
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Then
1 exterior angle = 360° ÷ 8 = 45° , so
x + 10 = 45 ( subtract 10 from both sides )
x = 35
