!!!The volume of a cylinder is 675π cm3. The radius of the base of the cylinder is 5 cm. What is the height of the​ cylinder?
kompoz [17]

Answer:

The answer is

<h2>27 cm</h2>

Step-by-step explanation:

Volume of a cylinder is given by

<h3>V = πr²h</h3>

where

h is the height

r is the radius

V is the volume

Since we are finding the height

h =  \frac{V}{\pi  {r}^{2} }

From the question

V = 675π cm³

r = 5 cm

Substitute the values into the formula and solve for the height

That's

h =  \frac{675\pi}{ {5}^{2}\pi }  \\  =  \frac{675\pi}{25\pi}  \\  =  \frac{675}{25}

We have the final answer as

27 cm

Hope this helps you

PLEASE HELP LIKE NOW IM TIMED.. WILL GIVE BRAINLIEST!!! In the figure, ΔABC ~ ΔDEF. Solve for x. Triangles ABC and DEF. Angles B
VLD [36.1K]
Use CPCTC
Congruent Parts of a Congruent Triangle are Congruent

∠B ≅ ∠E
AB <span>≅ DE
BC </span><span>≅ EF

AB = 20
BC = 24
EF = 6
DE = x

20/24 = x/6

Solve for x, cross multiply

24(x) = 20(6)
24x = 120
24x/24 = 120/24
x = 120/24
x = 5

x = 5, or A is your answer

hope this helps</span>
