Question

Начертите окружность с центром в точке о и радиусом равным 4 см провед ите диаметр АВ.Запишите чему равна длина диаметра АВ

Answer 1

Если радиус 4 см, значит диаметр 4*2=8 см

Answer 2

Drawing a Circle with a Given Center and Radius

To draw a circle with a center at point O and a radius of 4 cm, we can follow these steps:

1. Step 1: Mark the Center Point O - Use a ruler and a pencil to mark the center point O on the paper.

2. Step 2: Measure and Mark the Radius - Use a ruler to measure 4 cm from point O in any direction and mark a point on the circle. This point will be the edge of the circle.

3. Step 3: Draw the Circle - Use a compass to draw the circle by placing the compass point on the center point O and extending the pencil to the marked point on the circle. Rotate the compass 360 degrees to draw the complete circle.

Finding the Length of Diameter AB

The length of the diameter AB can be found by doubling the radius of the circle. Since the radius is 4 cm, the diameter AB will be:

Diameter AB = 2 * Radius Diameter AB = 2 * 4 cm Diameter AB = 8 cm

So, the length of the diameter AB is 8 cm.
