The diameter of the face-off circle on an ice-hockey rink is 30 feet. Find its area.

Answers

Answer:

The area is 706.86 ft sq  

Answer:

706.86 sq ft. (or 706.5 sq ft if 3.14 is used as pi)

Step-by-step explanation:

the formula for the area of a circle is πr2^. We know our diameter is 30 ft, and since radius is half of the diameter, that means our radius is 15 ft. Now we plug this into the formula, which would be 3.14x15^2. type this into the calculator to get our area of 706.5 sq ft.

(also peter could totally be a girl and I am misgendered a person)

Answer:

The answer is 5.7%

Step-by-step explanation:

So Peter bought the makeup set that was $30.

and had to pay $1.71.

1.71 of 30.

So you would divide 1.71 with 30.

(1.71/30)

equaling .057

Then you would multiply by 100 because there is 100% total, and so multiplying that you would move the decimal two times to the right, getting 5.7

Rashida is building a model of her city's downtown area. She is constructing part of an office building, as shown below. Each cube has a length of centimeter.

centimeter.

The width of the model building is
centimeter.

The height of the model building is
centimeter.

The volume of the model building is
cubic centimeter.

Answers

6-7 that’s ur awnser girl

Based on the model, we find the dimensions of the cube. The length of the model building is 2/3 centimeter. The width of the model building is 1/3 centimeter. The height of the model building is 1/2 centimeter. The volume of the model building is 1/9 cubic centimeter.

What are dimensions of a cube?

A cube is 3- dimensional shape with 6 equal sides, 6 faces, and 6 vertices in geometry. Each face of a cube is a square. In 3 – dimension, the cube’s sides are; the length, width, and height. Sides of a cube are all equal i.e. Length = Width = Height = a.

The length = breadth = height (of one cube) = 1/6 cm

The length of the model consist of 4 cubes.

Length of model building = 4 * 1/6 cm = 2/3 cm

The width of the model consist of 2 cubes.

Width of model building = 2 * 1/6 cm = 1/3 cm

The height of the model consist of 3 cubes.

Height of model building = 3 * 1/6 cm = 1/2 cm

Volume of the model (cuboid) =

= Length * breadth * height

= [tex]\frac{2}{3} * \frac{1}{3}*\frac{1}{2} = \frac{1}{9}[/tex]
