Answer:

Volume of cone =  234.45 cm³

Step-by-step explanation:

Given:

Diameter = 8 cm

Radius r = 8 / 2 = 4 cm

Height h = 14 cm

Find:

Volume of cone

Computation:

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)(3.14)(4)²(14)

Volume of cone =  234.45 cm³

<em>Answer</em>

a. Vertical shrink by a factor of 1/3

<em>Step-by-step explanation</em>

Function transformation

• a,f(x) vertically compresses f(x) when 0 < a < 1

Given the function:

f(x)=x^2

Multiplying f(x) by a = 1/3, we get:

\frac{1}{3}f(x)=\frac{1}{3}x^2=h(x)

Then, f(x) is vertically shrunk by a factor of 1/3

find the volume of cubical box . if the cost of painting of outer surface is rs 1440 at the rate rs 15 per mcube
bearhunter [10]
Surface of a cubical box=6(side²)

1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface  ⇒surface=cost of painting/rate

Data:
Rate=$15/m²
cost of painting=$1440

Surface=$1440/($15/m²)=96 m²

2)We find out the length of the side:

Surface of a cubical box=6(side²)

Data:
Surface of a cubical box=96 m2

Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m

3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³

Answer: the volume of this cubical box would be 64 m³.
