How many centimeters is the diameter of a 9 inch cake? How big is a 9 inch cake?

The diameter of the 9-inch cake is calculated as follows;

Imperial inch = 9 Diameter] is the distance between two points on the edge from the center of a flat figure or three-dimensional (e.g., circle, conical section, sphere, cube), usually represented by the letter "d".

Mathematical term] The straight line where the diameter is located is the axis of symmetry of the circle. The two endpoints of the diameter are on the circle, and the center of the circle is the midpoint of the diameter. Diameter divides a circle into two equal parts, and the middle segment is called the diameter (each part becomes a semicircle).

In our daily life, we will also see many other shapes of cakes, such as square, heart-shaped, peach-shaped, and animal-shaped. If it is a square 8-inch cake, then we can use its diameter (side length) as a benchmark of 18 cm. If it is a different shape, if it is a heart-shaped or special-shaped cake, we also need to use an 8-inch cake as the base, and then cut out the shape you need.

Suitable for the number of people

1 inch corresponds to about centimeters, and then let's look at the cross-reference information of the size of the cake and the corresponding number of people who eat it.

8-inch cake with a diameter of about 20 cm.

Originally, the cakes were round, and the cakes in the cake shop were also in "inches", and the "inches" of the cake referred to inches, so the daily 8-inch cake refers to the circle with a diameter of 8 inches.

The conversion relationship between the inch ( ) and the centimeter of the cake is: 1 (inch) inch of regret = . Therefore, the 8-inch cake is marked with a quasi-size = 8*.

1. The diameter of the nine-inch cake is.

2. Imperial one inch = centimeter, 9 * centimeter late grip. Cake is an ancient pastry that is made in an oven, and the cake is made with eggs, sugar, and wheat flour as the main ingredients. Take milk, juice, milk powder, powder, salad oil.

2. Calculation method, an inch in the imperial system is centimeter, and 9 times centimeter is equal to centimeter;

3. Diameter refers to the distance between two points from the center to the edge through a plane figure or three-dimensional such as a circle, a circle and a cone section, a sphere, a cube, usually represented by the letter d, the straight line where the diameter is located is the axis of symmetry of the circle, the two ends of the diameter are on the circle, and the center of the circle is the midpoint of the diameter. The diameter divides the circle into two parts of equal area, and the middle line segment is called the diameter, and each part becomes a semicircle.
