Find the surface area and the volume of the figure Round to the nearest tenth if needed.

elixir [45]

Answer:

See below

Step-by-step explanation:

Surface area:

S = 2(lw + lh + wh) + 2πrh
S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)

Volume:

V = lwh + πr²h
V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)

Hw 43 special right triangles

Nutka1998 [239]

Answer:

Step-by-step explanation:

Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2

we have answers as

8. u=16 and v = $8\sqrt{3}$

9) y=5 and x= $5\sqrt{3}$

10) tan 30 = $\frac{1}{\sqrt{3} }$

So y= $4\sqrt{3}$

x= $8\sqrt{3}$

11) a=22 and b=11

12) b=1.5 and a= $1.5\sqrt{3}$

13) y= $20\sqrt{3}$

and x=10

The heights of american men aged 18 to 24 are approximately normally distributed with a mean of 68 inches and standard deviation

Rudik [331]

A normal distribution is symmetrical about the mean. Therefore half of all young men are shorter than 68 inches.
