Question

Длина тела косатки 4 м, а средний радиус тела 0,7 м. Вычислить объём тела кита по формуле объёма (ГДЕ пи=3). Плотность кита равна примерно плотности воды (900 кг/м в кубе). Рассчитайте вес кита

Answer 1

Косатка, согласно условию задачи, имеет форму цилиндра.
Объём цилиндра находится по формуле
$V=\pi\cdot{R^2}\cdot{H}$

Радиус, в данном случае, равен 0.7 метра, а H=4 метра. То есть объём тела равен
$V=3\cdot0.7^2\cdot4=5.88 m^3$

Формула плотности
$\rho=\frac{m}{V}$

Выразим массу
$m=\rho\cdot{V}$

$m=900\cdot5.88=5292 kg$

Стрёмная задача, на самом деле. Слишком много приближений. Но это решение правильное, согласно условию

Answer 2

Calculation of the Volume of a Whale

To calculate the volume of a whale, we can use the formula for the volume of a sphere, where the radius of the sphere is equal to the average radius of the whale's body. The formula for the volume of a sphere is:

Volume = (4/3) * π * r^3

Given that the average radius of the whale's body is 0.7 m and π is approximately 3, we can substitute these values into the formula to calculate the volume of the whale.

Volume = (4/3) * 3 * (0.7^3) Volume = 4 * 0.7^3 Volume = 4 * 0.343 Volume = 1.372 cubic meters

Therefore, the volume of the whale's body is approximately 1.372 cubic meters.

Calculation of the Weight of the Whale

To calculate the weight of the whale, we need to multiply the volume of the whale's body by the density of the whale. Given that the density of the whale is approximately equal to the density of water, which is 900 kg/m^3, we can use this value in our calculation.

Weight = Volume * Density Weight = 1.372 * 900 Weight = 1234.8 kg

Therefore, the weight of the whale is approximately 1234.8 kg.

Please note that these calculations are based on the given information and assumptions. The actual weight of a whale may vary depending on various factors such as species, age, and overall body composition.
