Answer:
5,024 inches squared
Step-by-step explanation:
Since the area of a circle is pi r^2, we basically have to replace the r with 40, since it's the radius. Therefore when replaced, it would be pi(40)^2. This makes 1600pi. Pi is technically 3.14, so I multiplied 3.14 and 1600 to get 5,024 inches squared.
The answer is 4. You do 12 times 1/3. This is because this is important in order to find out the answer. The answer is 4.
If by P=5ft you mean the radius is 5 then c = 2pi r or c = 10pi or approx 31.4 ft
Answer:
Because the metric system is acknowledged by all countries except for the US, therefore, to put it only in a format understood by Americans would make it harder for the larger population of the scientific community to understand. If it's in the metric system, it can easily be understood for peer review and or involvement
