Depends on what you're looking at. Colors seem to have a role in how we feel, out heart rate. But being able to look at calming scenery, of bright greens and blues is calming because it's the colors of life, and our minds sees the colors and we instantly become more calm. Green is calming because it's color that is found quite frequently in nature, so essentially it's good.<span />

A water tank has the shape of an inverted cone (like an ice cream cone without ice cream). the tank is 10m high and has a radius

Nostrana [21]

we know that

the surface area of the top of the water is calculated with the formula of the area of a circle

$A=\pi r^{2}$

Step 1

Find the radius of the water tank in the middle of the tank

by proportion

$\frac{10}{3} =\frac{5}{x} \\ \\ 10*x=5*3\\ \\ x=\frac{15}{10} \\ \\ x=1.5m$

For h=5 m

the radius is equal to r=1.5 m

Step 2

Find the surface area

$A=\pi*1.5^{2}$

$A=7.07\ m^{2}$

therefore

the answer is

the surface area of the top of the water is $7.07\ m^{2}$
