What is the height of the cone below?<br><br> V = 45 in^3<br><br> B = 5in^2
Lapatulllka [165]

Answer:

The height of the cone is h = 27

Step-by-step explanation:

<u>Formula:</u>-

Step 1:-

The volume of the cone is  V=\frac{1}{3} (base)(height)

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

<u>Step 2</u>:-

by using formula, we get solution

45 = \frac{1}{3} (5)(h)

cross multiplication, we get

\frac{45 x 3}{5} =h

now simplification, the height of the cone is h = 27

lord [1]

Answer:

Такое тёплое место, но там, на улице,

Где ждут отпечатков наших ног,

Там сапоги сияют звёздной пылью.

Здесь пастыри и мягкое кресло,

Ослепительные сны под ярким солнечным шаром,

Курок не был нажат, когда было нужно.
