Find the volume of a right circular cone that has a height of 17.7 cm and a base with a diameter of 15.8 cm. Round your answer t

Lelu [443]

Answer:

$1156.8cm^3$

Step-by-step explanation:

The volume of a cone is given as:

$V =\frac{1}{3} \pi r^2h$

where r = radius

h = height of cone

The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).

Its volume is:

$V = \frac{1}{3} * \pi = 7.9^2 * 17.7\\ \\V = 1156.8cm^3$

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of

Romashka [77]

Answer:

Step-by-step explanation:

A = Surface area of the Earth = $1.5\times 10^8\ \text{km}^2$

Total number of people on Earth = 7.594 billion as of 2018 = $7.594\times 10^9$

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

$1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}$

$\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}$

$\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}$

So, 51 people will inhabit each square km of land area.
