Accuracy describes how close a measurement is to its actual value. Precision
is the ability of a measurement to be consistently reproduced. This means
that every time you measure you get close to the same results.Alley, Ben, and Sophia measured the circumference of a circular Student Circumference

Alley 224
Ben 223.5
Sophia 223.75tablecloth for trim. Their results are shown in the table.
Suppose the radius of the tablecloth is 35 inches. Describe the
accuracy and precision of their measurements.
Their measurements are precise because they consistently
achieved similar results. Their measurements are not accurate
because the actual circumference of the circle is 2π(35) or about 220 inches.- Measure the circumference of a cylinder. Compare your results
with two classmates who found the circumference of the same cylinder.
Describe the precision and accuracy of your results.
