Answer:

15/2π

Step-by-step explanation:

If the circumference is 15 inches, we can create an equation using the following formula:

Circumference of circle = 2 x π x radius

which is C = 2πr

Now, substituting our value of the circumference (15) into the equation, we get:

15 = 2πr

In order to find r, the radius, we must divide both sides by 2π, which makes r the subject. This cancels out the 2π on the right side, leaving us with:

15/2π = r

So the radius is 15/2π.

Write two expressions to show the total area of advertisement space on one page.
valina [46]

The area covered by the advertisement on the page is ab  \ unit^2.

<h3>What is the definition of area of a rectangle?</h3>

The area of a rectangle covers is the space it takes up inside the boundaries of its four sides. The dimensions of a rectangle determine its area. In general, the area of a rectangle is equal to the product of its length and breadth of the rectangle.

The formula of area of rectangle is length \times breadth unit^2

let the given page represents a rectangle.

We take the length of the advertisement is a unit and breadth of the advertisement is b unit.

The area of the advertisement =a \times b \ unit^2

                                                   =ab \ unit^2

Therefore, the area covered by the advertisement on the page is ab  \ unit^2

Helppppppppppppppppppppppppp
Rasek [7]

Answer:

A  40

Step-by-step explanation:

We can find angle K

J + K + L = 180  The angles of a triangle add to 180

50 + K + 90 =180

140 +K = 180

Subtract 140 from each side

140-140 + K = 180-140

K = 40

Since the triangles are congruent

J = P

K = N

L = M

We want to find N

K = N = 40

K = N

The beach ball we played with has a density of 10 grams per cubic centimeter
Wittaler [7]
Answer: does not make sense.

The statement " t<span>he beach ball we played with has a density of 10 grams per cubic centimeter" does not make sense.

 Reasoning.

Inflated beach balls have a very low density, they are pretty much only air, plus the weight of the ball per se. Certainly that density is much lower than the density of water.

Inflated beach balls fall slowly in the air because their density is very close to the density of air and float on water because their density is less than the density of water.

Being the density of pure water 1 g/cm^3 you can predict, without any calculation, that the density of the beach ball is less than that and never 10 g/cm^3 which is 10 times the density of pure water.
