Question

Задача 2 Клумба має форму круга радіусом 5 м. На клумбі висаджують кущі тро анд, відводячи під кожний кущ 0,8 м2 землі. Яку найбільшу кількість тро инд можна висадити на клумбі?

Answer 1

Ответ:

98 кустов роз.

Пошаговое объяснение:

π≈3,14

Sкл=πR²=5²*3,14=78,5м² площадь клумбы;

78,5:0,8≈98 кустов роз (округление до целых)

Answer 2

According to Google Translate, the text you entered is in Ukrainian and it means:

Answer in detail. Task 2 The flower bed has the shape of a circle with a radius of 5 m. On the flower bed, bushes of roses are planted, allocating 0.8 m2 of land for each bush. What is the largest number of roses that can be planted on the flower bed?

To solve this task, we need to find the area of the flower bed and divide it by the area allocated for each bush. The area of a circle is given by the formula $$A = \pi r^2$$, where $$r$$ is the radius. In this case, the radius is 5 m, so the area of the flower bed is $$A = \pi \times 5^2 = 25\pi \approx 78.54$$ m2. The area allocated for each bush is 0.8 m2, so the number of bushes that can be planted on the flower bed is $$N = \frac{A}{0.8} = \frac{25\pi}{0.8} \approx 98.17$$.

However, we cannot plant a fraction of a bush, so we need to round down the answer to the nearest integer. Therefore, the largest number of roses that can be planted on the flower bed is 98.
