Answer:

B) 12.25πm²  

Step-by-step explanation:

The formula for the <em>circumference</em> of a circle is

C = 2πr

The circumference of your circle is

C = 7πm

If we factor out a 2 from the 7, we get

C = (2 × 3.5)πm = 2π(3.5m)

Now, if we compare the two formulas, we see that

r = 3.5m

The formula for the <em>area</em> of a circle is

A = πr²

If r = 3.5m, then the area of your circle is

A = π(3.5m)² = 12.25πm²

Select the correct answer. Which statement best defines the term principal? A. It is an arrangement in which you buy now and pay
Hatshy [7]

Answer:

<u>The correct answer is C.  It is the original amount of money the bank loans the borrower.</u>

Step-by-step explanation:

Let's recall that are five basic elements for calculating the payment of a loan:

1. The principal. How much money you borrow.

2. The interest rate. How much money you will pay in addition to the principal.

3. The period of time. How long will it takes you to pay the loan.

4. The frequency of payment. Will you pay every month?, every quarter?, every year or maybe every two weeks?

5. Additional payments. When you have additional income seasonally and you want to lower either the period of time or the interests to pay.

Find the volume of this cylinder.
Lina20 [59]

Answer:

The answer is 3418.1 ft rounded to the nearest tenth.

Step-by-step explanation:

The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.

The area of the circular base can be calculated as

\pi \times  {r}^{2}

where r is the radius of the circular base, which is 8 ft.

The area of the circular base is

\pi \times  {8}^{2}  = 64\pi

We also know the height of the cylinder is 17 ft.

Hence, the volume of the cylinder is

64\pi \times 17 = 1088\pi = 3418.0528...

This will be rounded up to 3418.1 with the nearest tenth

A regression equation is obtained for a collection of paired data. It is found that the total variation is 20.711 , the explaine
galben [10]

Answer:

0.898

Step-by-step explanation:

The formula for the Coefficient of determination = ratio of explained variation to Total variation

From the above question, we have the following values

Explained variation = 18.592

Total variation = 20.711

The coefficient of determination = 18.592 : 20.711

= 18.592/20.711

= 0.8976872194

Approximately ≈ 0.898

Therefore, the coefficient of determination is 0.898
