A spherical iron ball 10cm in radius is coated with a layer of ice of uniform thickness that melts at a rate of `50c m^3//m in` . When the thickness of ice is 5cm, then find the rate at which the thickness of ice decreases.

A spherical iron ball 10 cm in radius is coated with a layer of ice of uniform thickness that melts at a rate of 50 cm^(3)//min. When the thickness of ice is 5 cm, then the rate at which the thickness of ice decreases, is:

A spherical iron ball 10 cm in radius is coated with a layer of ice of unirform thichness that melts at a rate of 50cm^3 /min. when the thickness of ice is 5 cm, then the rate at which the thickness of ice decreases, is

A spherical iron ball of radius 10cm, coated with a layer of ice of uniform thickness, melts at a rate of 100 pi cm^(3) // min.The rate at which the thickness decreases when the thickness of ice is 5 cm, is

A sphere of 10cm radius has a uniform thickness of ice around it. Ice is melting at rate 50 cm^3//min when thickness is 5cm then rate of change of thickness

A spherical ball of radius 10cm is enclosed by ice of iniform thickness in spherical shape.If ice melts at the rate of 50cm^(3)/min then the rate of decrease of thickness of ice when thickness of ice is 5cm is

A solid sphere of radius 6 cm is melted into a hollow cylinder of uniform thickness. If the external radius of the base of the cylinder is 5 cm and its height is 32 cm, find the uniform thickness of the cylinder.

A copper rod of diameter 2 cm and length 10 cm is drawn into a wire of uniform thickness and length 10 m. Find the thickness of the wire.

An open Can of oil is accidently dropped into a lake; assume the oil spreads over the surface as a circular disc of uniform thickness whose radius increases steadily at the rate of 10 c m//s e c . At the moment when the radius is 1 meter, the thickness of the oil slick is decreasing at the rate of 4\ m m//s e c , how fast is it decreasing when the radius is 2 meters.
