Hi! help me please, Thank you.
A spherical steel ball bearing has a diameter of 2.540 cm at 23°C.
(a) What is the diameter when its temperature is raised to 94°C?
cm

(b) What temperature change is required to increase its volume by 0.9%? I only need help on part b.Thank

• physics -

The subject is mispelled, again. Pleases get it right.

Volume is increased 0.9% when linear dmensions are increaed 0.3%, when the relative chance is much less than 1, as is the case here.
