Answer:

Step-by-step explanation:

1. This is a arithmetic sequence, so the equation is $a_{n}=a_{1}+(n-1)d$ .

$a_{1}$ is -33 and the d is -33.

So, the equation is $a_{n} = -33+(n-1)(-33)$ .

Mrs. Owens was making Thanksgiving dinner for 10

saul85 [17]

Well if she is making dinner for 10 people and each person want 2 pieces then you need to multiple 10 x 2 = 20. So she is going to need to make 20 pieces.

If each of her pumpkin pies only has 8 pieces then she is going to have to make 3 pies.

3 pies x 8 pieces = 24 pieces of pumpkin pie. So she has to make 3 pies because she needs 20 pieces since everyone wants 2.

In conclusion Mrs. Owens has to make 3 pies and she is going to have 4 pieces left over.

Given that circumference of a circle is 44m. Calculate it's area

dimaraw [331]

Answer:

Area=154.062 $m^{2}$

Step-by-step explanation:

As Circumference of a circle is given by;

$C=2\times \pi\times r$

As the circumference is 44m so we can calculate the value of r by using the above formula.

$44=2\times \pi \times r\\\\\frac{44}{2\pi} =r\\\\\implies r=\frac{22}{\pi} =7.003 m$

Now to Calculate the Area of a Circle.

As the area of a circle is,

$Area =\pi \times r^{2}\\ Area=\pi \times (7.003)^{2} \\Area=\pi \times 49.039\\Area=154.062m^{2}$
