The radius of a uranium (U) atom is 156 pm. What is its circumference?

Circumference of the uranium atom is 979.68pm

Explanation:

Given

Uranium Atom

Radius (r) = 156 pm

Required

Determine the circumference

This will be calculated using the circumference (C) of a circle

C = 2πr

Take π as 3.14 and substitute 156pm for r in the above formula.

C = 2 * 3.14 * 156pm

C = 979.68pm

Hence, the circumference of the uranium atom is 979.68pm
