Question

Найдите площадь круга с радиусом 10 см . (p=3)

Answer 1

S=πр в квадрате, т.е. площадь круга равна 3,14х100=314

Answer 2

3*10²=300 см² площадь круга

Answer 3

Calculation of the Area of a Circle with a Radius of 10 cm

To find the area of a circle with a radius of 10 cm, we can use the formula:

Area = π * r^2

where π is a mathematical constant approximately equal to 3.14 and r is the radius of the circle.

Substituting the given radius of 10 cm into the formula, we get:

Area = 3.14 * (10 cm)^2

Simplifying the equation, we have:

Area = 3.14 * 100 cm^2

Calculating the result, we find that the area of the circle is:

Area = 314 cm^2.

Therefore, the area of the circle with a radius of 10 cm is 314 square centimeters.
