Answer:
356 cm².
Step-by-step explanation:
Step one: The first thing to do here is to Calculate the area of rectangle. The area of the rectangle can be calculated by using the formula below;
Area of rectangle = width × length = 6 × 4 = 24 cm².
Step two: the next step is to calculate the area of the circle. The area of the circle can be calculated by using the formula below;
Area of a circle = (radius)^2 × π.
Area of a circle = (11)^2 × π = 380.13 cm².
Step three: the next thing to do is to calculate the area of the shaded region which is the difference between the Area of a circle and the Area of rectangle.
That is; 380.13 cm² - 24 cm² = 356.13 cm².
Answer:
A = 1, B = 1
Step-by-step explanation:
From the question
(2x+1)/(x²+x) = A/x + B/(x+1)
(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)
Equation the numerator
2x+1 ≡ A(x+1) +Bx
2x+1 ≡ Ax+A+Bx
From the above,
A = 1.
And,
2x = Ax+Bx................ Equation 1
A+B = 2
Substitute the value of A into Equation 1
1+B = 2
B = 2-1
B = 1
