What is the height of the cone below? V = 45 in^3 B = 5in^2

Lapatulllka [165]

Answer:

The height of the cone is h = 27

Step-by-step explanation:

Formula:-

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

Step 2:-

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

The measure of the angle of depression from the top of a 270 m building tweet park bench on the ground is 63° 43’.How far Where

Norma-Jean [14]

Answer:

547 m

Step-by-step explanation:

Given :

Angle of depression, θ = 63°43' ; 43/60 = 0.7167 = 63 + 0.7167 = 63.7167°

The height, h = 270

The distance of park bench from the building, d is given by :

Tan θ = opposite / Adjacent

Tan 63.7167 = d / 270

d = 270 * Tan 63.7167

d = 546.70459

d, distance of Park bench from building is 547 m
