The surface area of hemisphere is given by:
Where r is radius of hemisphere.
We are given diameter = 250 ft.
We know that radius = half of diameter.
Radius of dome = 1/2 (250) = 125 ft.
Now let us plug the value of radius in the formula,
Surface Area of dome = 98125 square foot.

...
The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.
<h3>What is the point implying?</h3>
Note that in the question, it was supplied that Otto intended to make a mixture of 12% butter fat.
Since:
Milk = 2% butter fat
Whipping cream = 30% butter fat.
This implies that the milk contains the smallest of butter fat and it also implies that Otto would require a lot more milk than cream, to be able to attain the 12% mixture.
This is known to be when point J is said to meet, and by using that data from point J, Otto require more of milk than the cream to get what he wants.
Therefore, The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.
