On the clock face, the trajectory of the minute and hour tips is circled, and the two circles (circles) are the same.

The analysis process is as follows:

The length of the minute and hour hands is not equal, so the area and circumference of the two are not equal.

Only the center of the circle is the same for the minute and hour hands.

Hello, Wonder Maiden

It's concentric circles.

The hour and minute hands coincide at (12) o'clock. When the hour and minute hands form a line, it is (6) o'clock.

There are 12 large squares, 60 small squares, and 1 large square with 5 small squares. The hour hand travels 1 block for 1 hour, the minute hand moves 1 block for 1 minute, and the minute hand moves 1 block for 5 minutes.

Several key angles on the dial of the clock:

9 o'clock in the morning: the hour and minute hands form an angle of 5261 degrees at 90 degrees. 12 o'clock sharp:

The hour and minute hands are angled at 0 degrees. 3 p.m. sharp: The hour and minute hands are angled at 90 degrees.

6 p.m. sharp: The hour and minute hands are angled at 180 degrees.

Because the pointer length is different, that is, the radius is different, so the perimeter and area are different, and the answer is the same center.

The type specifier indicates the data class differential type of the variable to which the pointer variable is directed; * indicates that this is a pointer variable; The variable name represents the defined pointer variable name, and its value is an address, for example: char*p1; Indicates that p1 is a pointer variable and its value is the address of a character variable.

The pointer refers to the address of the unit, and the content of the unit is stored in the data. In C, pointer variables are allowed to hold pointers, so the value of a pointer variable is the address of a memory cell or a pointer called a memory cell.

Pointer variables and their definitionsPointer variables are variables that store a memory address, and unlike other types of variables, they are specifically used to store memory addresses, also known as address variables. The general form of defining a pointer variable is: type specifier * variable name.

15 (1+1 12) = 13 and 11 13 points.

Answer: At 3:13 and 11 13, the position of the hour and minute hands is equal to the distance of 3.

After an hour on the seed surface, the tip of the minute hand has gone around, so it has walked 360 degrees, and the hour hand has not been simplified, so it is 1 12 180 = 15 degrees. Wei Pei.

The hour hand goes from 0 to 12 for a week, a total of 12 scales, and the trouser scale goes from 1 to 6, with 5 scales. Therefore, the length of the hour hand from the tip of the 1 to 6 needle is 5 12 of the length of its rotation

The hour hand from one o'clock to six o'clock is 5 to 12 of its rotation.

The hour hand goes from one to six, then he is 5 12 circumferences long.

The hour and minute hands coincide at (12) o'clock. When the hour and minute hands form a line, it is (6) o'clock.

Several key angles on the dial of the clock:

1) 9 o'clock in the morning: the hour and minute hands are at an angle of 90 degrees.

2) 12 noon sharp: the hour and minute hands are at an angle of 0 degrees.

3) At 3 p.m., the hour and minute hands are at an angle of 90 degrees.

4) 6 p.m. sharp: The hour and minute hands are angled at 180 degrees.

Recognize clocks: there are 12 numbers, seconds, minutes, hours, and grids on the clock face; The longest hand is the second hand, the second longest is the minute hand, and the shortest is the hour hand.

The 12 numerals divide the clock face into 12 large cells, each of which has 5 small cells, for a total of 60 small cells; The minute hand points to 12, and the hour hand points to the hour.

When the hour hand on the clock face coincides with the minute hand, it is (12), and when it is (6), the hour hand and minute hand form a straight line.

When the hour hand and the minute hand in the middle coincide, it should be zero hour when the hour hand and minute hand are the same.

Summary. Hello, please explain your problem in detail.

The hands on the clock face, at which time at 9 o'clock, the position of the hour and minute hands is equal to 6.

Hello, please explain your problem in detail.

If someone goes to wash up at 9 o'clock in the evening and finds that the distance between the hour hand and the minute hand is equal to the 6 figures, then what is the time for him to wash?

Hello, you can set the radius of the clock face to r, then you can calculate the distance that the hour hand travels per second is r 21600 and the minute hand travels the distance per second is r 1800 By the title, r 2+ r*x 21600= r- r*x 1800 solves x=10800 13 2610 seconds, so at 9:43:30, the position of the hour and minute hands is equal to the distance of 6.
