Question

площадь ткани которая пошла на изготовление зонта без учета отрезков равна сумме площадей треугольников междц спицами. надицте площадь ткани, необходимой для изготовления такого зонта, если высота каждого равнобедренного треугольника, проведенная к основанию, равна 64,4

Answer 1

Ответ:

Объяснение:

a=31(Условно)

h=64,4

1. S= 1/2 * ah
2. S= 31/2 * 64,4 = 15,5*64,4 = 998,2 × 12 =  11 978,4 cm2

Answer 2

Calculation of Umbrella Fabric Area

To calculate the area of fabric required for making an umbrella, we need to consider the sum of the areas of the triangles formed between the spokes. The height of each isosceles triangle, drawn to the base, is given as 64.4.

Let's assume the number of spokes in the umbrella is 'n'. Each spoke divides the umbrella into 'n' equal parts, creating 'n' isosceles triangles.

To find the area of each triangle, we need to know the length of the base. Unfortunately, the length of the base is not provided in the question. Without this information, it is not possible to calculate the exact area of the fabric required for the umbrella.

If you have any additional information or specific measurements, please provide them so that I can assist you further.
