An inverted cone is of height 60cm and radius 15cm. Water is poured into the empty cone at a constant rate of 24cm^3/s. After t seconds the height of the water is h cm. Calculate the rate of change of the height of the water level when (i) h = 20
(ii) the cone is one-third full

(please answer both parts!)

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

107 units
