13. The radius of Earth is approximately 6.4 x 100 m. Use the formula V = 4/3pr^3

romanna [79]

<u>We are given</u>

Radius of Earth; 6.4 x 100 meters = 640 meters

Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

$\implies \text{Volume of sphere =} \ \dfrac{4\pi r^{3}}{3}$

When we substitute the radius in the formula, we get;

$\implies\text{Volume of sphere} = \dfrac{4\pi (640)^{3}}{3}$

$\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}$

Take π as 3.14

$\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}$

$\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}$

Simplify the numerator;

$\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}$

$\implies \text{Volume of sphere} = \dfrac{3292528640}{3}$

Divide the numerator by 3;

$\implies \text{Volume of sphere} = \dfrac{3292528640}{3}$

$\implies \text{Volume of sphere} = \boxed{1097509546.67 \ \text{m}^{3} } \ \ \ (\text{Estimated})$

suppose an architect draws a segment on a scale drawing with the end points (0,0) and (3/4,9/10). the same segment on the actual

dlinn [17]

Let the segment be represented by AB where A(0,0) = $A(x_{1}, y_{1})$ and B(3/4,9/10) = $B(x_{2}, y_{2})$ .

The length of the segment drawn by architect can be calculated using distance formula:

AB = $\sqrt{}( x_{2}- x_{1})^ {2} + (y_{2}- y_{1})^ {2}$

$AB=\sqrt{(3/4-0)^{2}+(9/10-0)^{2}$

$AB=\sqrt{9/16+81/100} \\$

$AB = (6\sqrt{61})/40$

Similarly, Let the actual end points of segment be AC where A(0,0) = $A(x_{1}, y_{1})$ and C(30,36) = $C(x_{2}, y_{2})$ .

The length of the original segment can be calculated using distance formula:

AC = $\sqrt{}( x_{2}- x_{1})^ {2} + (y_{2}- y_{1})^ {2}$

$AC=\sqrt{(30-0)^{2}+(36-0)^{2}$

$AC=\sqrt{900+1296} \\$

$AC = (6\sqrt{61})$ .

Thus, the actual length is 40 times the length of the segment drawn by the architect.

Thus, the proportion of the model is 1:40

I need help with this thank you!

Answer: m<AOB is 60 degrees.

Step-by-step explanation: If BCD is 30 degrees, it intercepts the arc BA, and therefore, any angle that intercepts an arc is half of the arc it intercepts. Thus, AOB is 60 degrees.
