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.

Answers

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]
