Answer:
The volume of water in the vase is
Step-by-step explanation:
A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:
r = 3 / 2 = 1.5 inches
To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.
The volume of a cylinder is given as:
The volume of the vase will be:
Hence, the volume of the water in the vase when it is 9/10 filled is:
Approximating to the nearest cubic inch, the volume of water in the vase is
There are no real numbers that can do that job.
The numbers are
<em> 1.5 + i √7.75</em>
and
<em>1.5 - i √7.75</em>
These are called 'complex numbers'. The symbol ' i ' stands for √-1 .
==================================================
If either the ' 3 ' or the ' 10 ' was actually supposed to be negative,
then the two numbers would be<em> 2 </em> and<em> -5 .</em>
