Question

В любом цирке мира диаметр арены 13 м. Какую площадь в цирке занимает арена?

Answer 1

ПиR ^2=3.14*6.5^2=132.665 m^2

Answer 2

Calculating the Area of the Circus Arena

To calculate the area of the circus arena, we can use the formula for the area of a circle: πr^2, where r is the radius of the circle. Since the diameter of the arena is given, we first need to find the radius.

The formula for converting diameter to radius is: radius = diameter / 2.

Given that the diameter of the arena is 13 meters, we can calculate the radius as follows:

radius = 13 / 2 = 6.5 meters.

Now, we can use the formula for the area of a circle to find the area of the circus arena:

Area = π * (radius)^2.

Calculation

Area = π * (6.5)^2.

Result

Area ≈ 132.73 square meters.

This calculation is based on the standard formula for the area of a circle and the given diameter of the circus arena. [[8 #]]
