Answer: 804.25cm
Step-by-step explanation:
V=πr2h/3
pi= 3.14
r=8cm
h= 12cm
Slot the values
3.14× (8x8) × 12/3
3.14 × 64 x 4
V= 804.25cm
Using translation concepts, the equation of g(x) is given as follows:

<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the parent function is given by:

For a horizontal compression by a factor of 1/5, we have to find f(1/5x), hence:

For a vertical stretch by a factor of 7, we have to multiply by 7, hence:

For a reflection in the y-axis, we have to find g(-x), hence:

For a translation of 10 units left, we have to find g(x + 10), hence:

For a translation of 1 unit down, we have to subtract one, hence:

The formula for compound interest is:

Given data:

a. After ten years, that is t = 10 years, the amount in the account will be

b. After twenty years, that is t = 20 years, the amount in the account will be:

c. The time it takes for Harry's initial account value to double will be:

Therefore, the time it takes Harry's initial account to double is approximately 11 years
