V = $\pi$ r^2h/3

V = 3.14 x 4^2 x 6/3 (remember r is 1/2 of the diameter)
V = 3.14 x 16 x 2
V = 100.5

In ∆MNP, m∠N = 90º, NH – altitude, m∠P = 21º, PM = 4 cm. Find MH.

Sveta_85 [38]

Answer:

0.51 cm

Step-by-step explanation:

In right triangle MNP, MP = 4 cm, m∠N = 90°, m∠P = 21°

By the sine definition,

$\sin \angle P=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{MN}{MP}\\ \\MN=MP\sin \angle P\\ \\MN=4\sin 21^{\circ}\approx 1.43\ cm$

Now, consider right triangle HMN (it is right because NH is an altitude). By the cosine definition,

$\cos \angle M=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}=\dfrac{MH}{MN}\\ \\MH=MN\cos \angle M$

In the right triangle, two acute angles are always complementary, so

$m\angle M=90^{\circ}-m\angle P=90^{\circ}-21^{\circ}=69^{\circ}$

Thus,

$MH=1.43\cos 69^{\circ}\approx 0.51\ cm$

A road sign says that there is an exit in 3/4 of a mile. How many metres is this? (Use the Unit Conversions in your formula shee

viva [34]

I think we will need to use the 1mile=5280ft and the 1ft=30.48cm and the 1metre=100cm

so
3/4 mles=3/4 times 5280=3960ft
1ft=30.48cm
times both sides by 3960
3960ft=120700.8cm

1metre=100cm
1/100meter=1cm
times both sides by 120700.8
1207.008meter=120700.8cm=3/4mile

answer is 1207.008 meters
round

1207 meters
