Answer: No

Step-by-step explanation: You have to divide it by two to to have the radius.

1. A line joining the two sides of a circle is called diameter.

2. This line actually divide the circle into halves.

3. The radius of a circle is the length of the circle from the centre position.

5. The radius is half the dimension of diameter.

6. Now we can prove that radius(r) is equal to diameter/2

r=d/2.

No. In fact, you divide it into two.

So let's say the diameter is 10 cm.

To get the radius, you halve it or divide by two.

10 ÷ 2 = 5 cm

The radius of a circle with a 10 cm diameter is 5 cm.

A contractor needs to put a carpet in the hallway of a house, the diagram of the houses is below.All of the sides of the figure

Vera_Pavlovna [14]

Break it into squared and rectangles and find the area of those first then add it all together

For your square you would get 16 ft squared

For your rectangle you would get 32 ft squared

For your other rectangle you would get 32 ft squared as well

Then add those all together to get the full answer

80 ft squared

Hope this helps :)

The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?

Alexxx [7]

Answer:

The correct answer is 14.5 centimeters on the map would be the distance between these two cities.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance between two cities = 87 kilometers

Scale of the map = 1:600,000

2. What is the distance between them on a map with that scale?

For finding out the answer to this question, we need to:

A. Convert 87 kilometers to centimeters, that is the average distance measurement of the maps, this way:

87 kilometers = 87,000 meters (multiplying by 10³)

87,000 meters = 8'700,000 centimeters (multiplying by 10²)

B. Now we divide the measurement in centimeters by the scale, this way:

8'700,000/600,000 = 14.5

The correct answer is 14.5 centimeters on the map would be the distance between these two cities.

Help what is the answer ?? What is the is the translation coordinate

nasty-shy [4]

Answer: (x - 3, y - 6) or S(-5 -3, 6 -6)

First we have to figure out how many spaces left to right (x-axis) and how many spaces up and down (y-axis) will get us to S'

x-axis: -5 - 3 = -8

y-axis: 6 - 6 = 0

Now we just add this to the original coordinate to give us the translation coordinate:

S(-5, 6) → S(-5 -3, 6 -6)
