Question

Write the formula used to find the total surface area of a water drop?

Answer 1

Answer:

4pi²

Step-by-step explanation:

Water drops are almost spherical when then fall.

so in the above equation, the surface area of a sphere is given.

Have a good day !

Answer 2

Total Surface area of water drop is $4\pi r^2$.

Step-by-step explanation:

We need to find the Total surface area of a water drop.

Solution:

Now we know that;

The water droplets are in spherical in shape.

Hence we will use the formula of sphere to find the surface area of the water drop.

Now we know that;

Total surface area of the sphere is given by 4 times π times square of the radius.

framing in equation form we get;

Total surface area of the sphere = $4\pi r^2$

Hence Total Surface area of water drop is $4\pi r^2$.
