Round your final answer to the nearest hundredth.
Answer:
128.86 square centimetres
Step-by-step explanation:
I will assume that the shaded region is the area in between the circle and the rectangle.
All we have to do is find the area of the circle and subtract it from the area of the rectangle.
Area of a circle is given as:
where r = radius
The radius of the circle is 1 cm, so, the area of the circle is therefore:
= 3.14 square centimetres
The area of a rectangle is given as:
A = L * B
The dimensions of the rectangle are 11 cm by 12 cm. The area of the rectangle is:
A = 11 * 12 = 132 square centimetres
The area of the shaded part is therefore:
A = 132 - 3.14 = 128.86 square centimetres

Step-by-step explanation:
The solution to the given quadratic equation buy factoring is: x = -7 or 7
A quadratic equation is an equation of degree 2 and has the standard form: ax² + bx + c = 0, with a ≠ 0
We can solve quadratic equations by:
- Completing the square
- Quadratic formula
- Factoring
We are given the quadratic equation as:
x² - 49 = 0
Factoring this gives us:
(x + 7)(x - 7) = 0
Thus:
x - 7 = 0 or x + 7 = 0
x = -7 or 7

If David, Malachy and Paul share some sweets in the ratio 4:3:3 then Paul get 7.2 number of sweets
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that David, Malachy and Paul share some sweets in the ratio 4:3:3
All three shared 24 sweets together.
Let x be the number of sweets
4x+3x+3x=24
Add the like terms
10x=24
Divide both sides by 10
x=2.4
Now paul has 3x sweets so 3×2.4=7.2
Hence, Paul get 7.2 number of sweets
