A science museum has a spherical model of the earth with a diameter of 6.5 m. What is the volume of the model? Use 3.14 for and

natka813 [3]

radius = diameter/2

radius = 6.5/2 = $\frac{13}{4}$ m

<span>volume </span> $= \frac{4}{3}$ x $\pi$ x (radius)³

$= \frac{4}{3}$ x $\pi$ x $( \frac{13}{4})^3$

$= \frac{4}{3}$ x $\pi$ x $\frac{2197}{64}$

$= \frac{2197}{64}$

= 144 cubic meters

Find the measure of DB (a curvy line is on top of DB btw)

klasskru [66]

Answer:

Arc DB = 146

x = 5

Step-by-step explanation:

Remark

The relationship between the large arc, the small arc and the intersecting angle is

1/2 (large arc - small arc) = intersecting angle.

Givens

Large arc = 25x + 21

Small arc = 96

Solution

1/2*(25x + 21 - 96) = 5x*2 Multiply both sides by 2

25x + 21 - 96 = 10 x Combine

25x - 75 = 10x Subtract 25x from both sides

-75 = 10x - 25x

-15x = -75

x = 5

DB = 25x + 21

DB = 25*5 + 21

DB = 125 + 21

DB = 146

Tell me if this is not in the choices.
