The volume of a cylinder is

V = (1/3) π (radius)² (height) .

It doesn't matter whether it's straight, or leaning over like this one.

V = (1/3) π (4 m)² (6 m)

V = (1/3) π (16 m²) (6 m)

V = (1/3) π (96 m³)

==> V = 32 π m³

Volume = 1/3 * pi * r^2*h
= 1/3 + pi * 4*2 * 6
= 8pi m^3

What is the growth factor associated with the following growth rate: 30% decrease

fenix001 [56]

Given:

Growth rate = 30% decrease

To find:

The growth factor associated with the given growth rate.

Solution:

The general exponential function is:

$y=a(1+r)^x$

$y=a(b)^x$

Where, a is the initial value, r is the growth rate in decimal and $b=1+r$ is the growth factor.

It is given that the growth rate is 30% decrease. So,

$r=-30\%$

$r=-\dfrac{30}{100}$

$r=-0.3$

Now,

$b=1+r$

$b=1+(-0.3)$

$b=1-0.3$

$b=0.7$

Therefore, the growth factor is 0.7.

By comparing the perimeters, we can deduce the scaling factor:

$k = \dfrac{34}{20} = 1.7$

The areas scale with the square of the scaling factor, so the new area is

$19.6 \cdot 1.7^2 = 56.644$
