The diameter is 48 feet. The radius is half of the diameter, so it is 24 feet. The area can be found using the formula pi r ^ 2. So, the area is 576 pi
Answer: Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.
Step-by-step explanation:
The empirical rule says that roughly 99.7% of the population is within 3 standard deviations of the mean.
Start at the center 60 which is the mean. Add on 3 standard deviations
60 + 3*4.5 = 73.5
and subtract off 3 standard deviations from the mean
60 - 3*4.5 = 46.5
So roughly 99.7% of the population of cattle has horn lengths between 46.5 inches and 73.5 inches
<h3>Answer: Choice D. 46.5 in - 73.5 in</h3>
