The answer should have been 8.6 that was wrong but it is okay you were close
Answer:
area: 41.04 cm² ; perimeter 35.8 cm
Step-by-step explanation:
Perimeter of shaded area = 1/4 perimeter of circle + line AC = ¼ * 3.14 * 2 * 12 + √(12² + 12²) = 18.84 + 12√2 cm = 35.8 cm
Area of Shaded Region = 1/4 area of circle - area of triangle = ¼ * 3.14 * 12² - ½ . 12 * 12
= (¼ * 3.14 - ½) * 12² = 41.04 cm²
Answer:
Perimeter = 10x + 8 units.
Area = 6x^2 + 13x - 5 units^2.
Step-by-step explanation:
The perimeter is 2*length + 2*breadth
= 2(2x + 5) + 2(3x - 1)
= 4x + 10 + 6x - 2
= 10x + 8 units.
The area = length * breadth
= (2x + 5)(3x - 1)
= 6x^2 - 2x + 15x - 5
= 6x^2 + 13x - 5 units^2.
Answer:
21 is 84% to 25, so there would be 25 total questions on the test
Answer:
34+(-12) =22
Step-by-step explanation:
because they said that adding numbers but they didn't said that negative Or positive. so i took those numbers
