Draw the largest circle and semicircle in a rectangle with a length of 2 Om and a width of 5 m, and

This is a rectangle with a length of 20 cm, and if you draw a circle and a semicircle, its circumference and area can be calculated.

Do we draw the largest circle or semicircle in a rectangle with a width of 20 and 15? Of course.

Hello, your problem is to draw the largest circle inside a rectangle with a length of 20 meters and a width of 15 meters. Then the radius of the circle is the largest value. 15, that is, the diameter is 15.

The circumference of the circle is equal to 15 factions. The area of the circle is equal to 15 2 brackets squared multiplied by pie.

In fact, this is very simple, draw the largest circle in it, its diameter is 15 meters, the largest semicircle, its diameter is 20 meters, with these data, of course, you can calculate their respective perimeters and areas.

Is the width of the rectangle 5 meters or 15 meters, if it is 5 meters.

Take pi as .

The largest circle, with a diameter of 5 meters.

The circumference is. 5* meters.

The area is. 5 2) 2* square meters.

The largest semicircle with a radius of 5 meters.

The circumference is. 5*(2+m.)

The area is. 5 2* sq.m.

The rectangle with a length of 20 meters and a width of 15 meters draws the largest radius of the circle.

Generally, there should be many versions of this perimeter area, and you can check it on the Internet.

Draw the largest semicircle in a rectangle 4 cm long and 2 cm wide, and find the perimeter and area of the rest of the part.

2) Circumference: cm).

Area: = square centimeters).

Answer: The circumference of this semicircle is centimeters, and the area is square centimeters

The circumference of the rest: half the circumference of the circle with the length of the rectangle + two widths + the radius with the width as the radius.

The area of the rest: the area of the rectangle - half of the area of the circle with the radius of width (that is, the area of the semicircle).

The length is the diameter and the width is the radius.

The circumference of the semicircle is centimeters.

Area: = square centimeters).

Solution: In a rectangle with a length of 3 cm and a width of 2 cm, draw the largest spring and wild circle, then the diameter of the circle is 2 cm in diameter, so the radius is 1 cm

Circle area = square centimeters.

The math tutoring team will call you the answer.

According to the topic, the diameter of the circle = the width of the rectangle = 6 cm to make a filial piety talk.

The area of the circle = the square centimeter of the sail of the sail)

Draw the largest semicircle in a rectangular Hu with a length of 6 cm and a width of 2 cm, and find the circumference of this semicircle.

Half trousers source talk late circle radius 2 cm

Circumference = 2x2 + 4 2 = 4 + 2 cm is approximately equal to cm

Girth: cm.

Area: = square centimeters).

Draw a semicircle with a diameter of 6 cm. The radius is only 3 cm, and a rectangle 6 cm long and 3 cm wide is enough.
