Answer:

The area of the piece of paper is 466 cm²

Step-by-step explanation:

First you would want to find the area of the rectangle

39x20=780 cm²

Both semi-circles are the same, so you can just find the area of the whole circle

The diameter is 20 cm so you would use 10 as the radius

A=πr²

A=3.14x10²

A=3.14x100

A=314

Then you have to subtract the area of the circle from the area of the rectangle.

780-314=466

The area of the piece of paper is 466 cm²

A circular region has a population of about 260000 people and a population density of about 135 people per square mine . find th
ValentinkaMS [17]

Answer:

24.76 mine

Step-by-step explanation:

The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:

260000/135 = 1925.93

The area would be 1925.93 square mine

We know that the area is given by:

A = pi * r ^ 2

we solve to r

r ^ 2 = A / pi

r ^ 2 = 1925.92 / 3.14

r ^ 2 = 613.3

r = 24.76

the radius is equal to 24.76 mine

Find the measure of each angle indicated
zaharov [31]

Answer:

For #6, it is 81 degrees, and for #8, it is 100 degrees.

Step-by-step explanation:

For #6, it is on the opposite side, so 81 degrees

For #8, it is also on the opposite side, so 100 degrees

Whenever there are parallel lines going horizontally, the angles measure the same on opposite sides, and to find the measure of an angle next to another angle, subtract it from 180.

If pis inversely proportional to the square of q, and p is 23 when q is 4, determine p
Misha Larkins [42]

Answer:

p\ =\ 92

Step-by-step explanation:

Given

p\ \alpha\ \frac{1}{q^2}

p =23; q=4

Required

Find p, when q = 2

We have:

p\ \alpha\ \frac{1}{q^2}

Express as equation

p\ =\ \frac{k}{q^2}

Make k the subject

k =pq^2

When: p =23; q=4

k =23 * 4^2

k =368

When q = 2, we have:

p\ =\ \frac{k}{q^2}

p\ =\ \frac{368}{2^2}

p\ =\ \frac{368}{4}

p\ =\ 92
