area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
a moderate estimate, not expensive, reasonable in price
A reasonable estimate is 1000. The actual total is 1016.
A reasonable estimate of the sum of 78 and 119 is 197.

A circle with a radius of 12 inches has a circumference of 75.4 inches.
It is: 16*pi square cm
The circumference is 50.3 inches.

Scandium empirical atom radius: 160 pm Scandium calculated atom radius: 184 pm
The radius of an oxygen atom is approximately 0.65 angstroms.

Estimate the answer. If the calculated answer is close to the estimate then it is reasonable.
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
No 100 is not a reasonable estimate
12 centimetres is a reasonable estimate.
