The volume of the globe is 38808 cube cm.

Step-by-step explanation:

Given,

The diameter of the globe = 42 cm

The radius (r) = 42÷2 cm = 21 cm

To find its volume.

Formula

The volume of a sphere of radius r = $\frac{4}{3}$ π $r^{3}$

Now,

Volume = $\frac{4}{3}$ × $\frac{22}{7}$ × $21^{3}$ cube cm

= 388080 cube cm

Need help with my work pleasem

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
: . $1 \frac{1}{2} / \frac{3}{4} = 2
$

Thus one can say m would be
$\frac{1}{2} * 2 = 1$

And N would be
$\frac{5}{6} * 2 = \frac{10}{6}$

Solve for x in simplest form 15 = 1/3(x+9)

Lorico [155]

Heya!

Your question states: Solve for x in simplest form 15 = 1/3(x+9)

Answer: X = 36

<em>Numerical Explanation:</em>

1. Step by step

I. 15 = 1/3(x+9)

2. Simplify both sides of the equation:

II. 15 = 1/3x + 3

3. Flip the equation:

III. 1/3x + 3 = 15

4. Subtract 3 from both sides:

IV. 1/3 x +3 = 15

-3 -3

5. Multiply both sides by 3:

V. 3 * (1/3 x) = (3) * (12)

6. Final answer:

VI. x = 36
