Answer:
The options are unclear but the answer is 8^2π square feet or 64π sqfeet
Explanation:
Area of a circle is denoted by: πr^2 where r is the radius of the circle.
In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2
= 16/2 = 8 feet.
Thus, the radius = 8 feet.
Hence, Area of a circle = πr^2
= π × 8^2
= 64π or 8^2π sqfeet.

Answer:
Explanation:
It is the lactic acid which makes milk taste sour. Pasteurising milk kills off harmful bacteria and greatly reduces the number of lactobacillus ensuring that milk will last up to three weeks in a fridge. Lactobacillus is a very useful bacterium as the acidic conditions it creates makes a milk protein called casein turn to curd.
