Question

Радиус круговой пластины равен 15 см. найдите площадь пластины.

Answer 1

S=п*R*R=3,14*15*15=706,5 см2

Answer 2

Calculation of the Area of a Circular Plate

To find the area of a circular plate, we can use the formula for the area of a circle, which is given by:

Area = π * r^2

where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

In this case, the radius of the circular plate is given as 15 cm. Therefore, we can substitute this value into the formula to calculate the area:

Area = π * (15 cm)^2

Calculating the area using the given radius of 15 cm:

Area = 3.14159 * (15 cm)^2

Simplifying the calculation:

Area ≈ 3.14159 * 225 cm^2

Evaluating the expression:

Area ≈ 706.8585 cm^2

Therefore, the area of the circular plate is approximately 706.8585 cm^2.

Please note that the value of π has been rounded for simplicity.
