58/2 = 29

w +2w+2 = 29

3w+2 =29

3w = 27

w = 27/3 = 9

width = 9

length = 2*9=18+2 = 20

20+20+9+9 = 58

Length = 20 feet

width = 9 feet

Step-by-step explanation:

Given

The composite object

Required

The volume

The object is a mix of a cone and a hemisphere

Such that:

$r = 10cm$ ---- radius (r = 20/2)

$h = 19cm$

<u>Hemisphere</u>

$r=10cm$

The volume of the cone is:

$V_1 = \frac{1}{3}\pi r^2h$

$V_1 = \frac{1}{3}\pi * 10^2 * 19$

$V_1 = \frac{1900}{3}\pi$

The volume of the hemisphere is:

$V_2 = \frac{2}{3}\pi r^3$

$V_2 = \frac{2}{3}\pi 10^3$

$V_2 = \frac{2000}{3}\pi$

So, the volume of the object is:

$V = V_1 + V_2$

$V = \frac{1900}{3}\pi + \frac{2000}{3}\pi$

$V = \frac{3900}{3}\pi$

$V = 1300\pi$

$V = 1300 * 3.14$

$V = 4082$

What is -3 1/3 = -1/2g

Firdavs [7]

Answer:

g = 62/3 or

$g = 20 \frac{2}{3}$

Step-by-step explanation:

$- \frac{31}{3} = - \frac{1}{2} g \\ - \frac{31}{3} \times ( - 2) = g \\ \frac{62}{3} = g \\ g = \frac{62}{3} \\ g = 20 \frac{2}{3}$
