Question

Две окружности имеют общий центр радиус одной окружности 6см а радиус второй составляет семь двадцатьчетвертых диаметра первой начертите эти окружности

Answer 1

Диаметр 1 окр. - 6 · 2 = 12 см
радиус 2 окр. - 12 · 7/24 = 7/2 = 3,5 см
диаметр 2 окр. - 3,5 · 2 = 7 см
вторая находится в первой

Answer 2

Drawing Two Circles with Common Center

To draw two circles with a common center, we need to follow these steps:

1. Start by drawing a point on a piece of paper. This point will represent the center of both circles. 2. Use a compass to draw the first circle. The radius of the first circle is given as 6 cm. Place the compass on the center point and draw a circle with a radius of 6 cm. 3. To draw the second circle, we need to determine the radius. The radius of the second circle is given as seven twenty-fourths (7/24) of the diameter of the first circle. Since the diameter of a circle is twice its radius, we can calculate the radius of the second circle as follows:

Radius of the second circle = (7/24) * (2 * 6 cm)

Simplifying the expression, we get:

Radius of the second circle = (7/24) * 12 cm

Therefore, the radius of the second circle is 3.5 cm.

4. Place the compass on the center point again and draw a second circle with a radius of 3.5 cm.

Now you have successfully drawn two circles with a common center. The first circle has a radius of 6 cm, and the second circle has a radius of 3.5 cm.
