Use the formula for a cylinder r=4 h=8 v?

zzz [600]

Answer:

$\large\boxed{V=128\pi\approx401.92}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2h$

We have r = 4 and h = 8:

$V=\pi(4^2)(8)=\pi(16)(8)=128\pi$

$\pi\approx3.14\to V\approx(128)(3.14)=401.92$

How do I solve for w?

LenaWriter [7]

Answer:

w = 8

Step-by-step explanation:

Based on the altitude theorem of a right triangle, we have:

w + 4 = √(24*6)

w + 4 = √144

w + 4 = 12

w + 4 - 4 = 12 - 4

w = 8

Roadsign cast of shadow that is 4 feet tall at the same time a 6 foot man standing next to the sign cast a shadow of those 2.4 f

Tanzania [10]

Answer:

10 feets

Step-by-step explanation:

Given that:

Road sign shadow (Rs) = 4 feets

Height of man (Hm) = 6

Man shadow (Ms) = 2.4 feets

Height of road sign (Hr) = x

Height of road sign / shadow of road sign = height of man / shadow of man

Hr/Rs = Hm / Ms

x / 4 = 6 / 2.4

Cross multiply :

4*6 = 2.4*x

24 = 2.4x

x = 24 / 2.4

x = 10 feets

Hence, height of road sign = 10 feets
