Question

Начертите окружность с радиусвми , равными 2см, 4см , 5мм. чему равен диаметр в каждой окружности плиззззз

Answer 1

D=2*R
2 х 2 = 4 см
4 х 2 = 8 см
5 х 2 = 10 мм = 1 см

Answer 2

D=2r
D=2*2=4 cм
D=4*2=8 см
D=5*2=10 мм

Answer 3

Drawing Circles with Different Radii and Calculating Diameters

To draw circles with different radii and calculate their diameters, we can use the formula for the diameter of a circle, which is twice the radius. Let's calculate the diameters for circles with radii of 2 cm, 4 cm, and 5 mm.

1. For a circle with a radius of 2 cm: - The diameter is calculated as: 2 * radius - Therefore, the diameter is: 2 * 2 cm = 4 cm

2. For a circle with a radius of 4 cm: - The diameter is calculated as: 2 * radius - Therefore, the diameter is: 2 * 4 cm = 8 cm

3. For a circle with a radius of 5 mm: - The diameter is calculated as: 2 * radius - Therefore, the diameter is: 2 * 5 mm = 10 mm

So, the diameters of the circles with radii of 2 cm, 4 cm, and 5 mm are 4 cm, 8 cm, and 10 mm respectively.
