A spherical iron ball of radius 10 cm, coated with a layer of ice of uniform thickness, melts at a rate of 100

\pi \;\mathrm{c}{\mathrm{m}^3}/\mathrm{min}

.The rate at which the thickness of decreases when the thickness of ice is 5 cm, is

View answer and explanation

Correct option: A

1cm/min

Option A (1cm/min) is correct because it represents the rate at which the thickness of the ice decreases, calculated using related rates.
