Question

Найдите площадь круга с диаметром 14 см.Число п округлите до десятых.

Answer 1

Calculation of the Area of a Circle

To find the area of a circle with a diameter of 14 cm, we can use the formula:

Area = π * (radius)^2

Since the diameter is given, we need to find the radius first. The radius is half the value of the diameter. Therefore, the radius of the circle is 14 cm / 2 = 7 cm.

Now, we can substitute the radius value into the formula to calculate the area:

Area = π * (7 cm)^2

To get the value of π, we will use the approximation of π as 3.14, as mentioned in the search results.

Area = 3.14 * (7 cm)^2

Calculating the area:

Area = 3.14 * 49 cm^2

The area of the circle with a diameter of 14 cm is approximately 153.86 cm^2.
