Answer:

49π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 14, so r = 14 ÷ 2 = 7, then

A = π × 7² = 49π cm²

Answer:

49pi cm^2

Step-by-step explanation:

$a = \pi \: {r}^{2}$

Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7

A = pi × 7^2

A= pi × 49cm^2

The population in the trapezoid-shaped region shown is about 3000 people. How many people are there per square mile?

Anastasy [175]

Answer: $\frac{3,000}{A}$

Step-by-step explanation:

<h3> Since the figure is not attached, below you can see a general explanation of the procedure to solve the exercise: </h3>

For this exercise you can apply the following formula, which is used to calculate the area of a trapezoid:

$A=\frac{h(B+b) }{2}$

Where "B" and "b" are the bases of the trapezoid and "h" is the height.

So, substituting values into the formula and evaluating, you can find the area of trapezoid-shaped region.

Since the population in the trapezoid-shaped region is about 3,000 people, you can find the number of people per square mile dividing the population by the area of the region.

Then, the following expression represents the number of people per square mile in that region:

$\frac{3,000}{A}$

Answer: C) 25

Step-by-step explanation:

x²+10x+ __=16+ __

Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.
