This is a question from Khan Academy: A company makes spherical tanks that store chemicals. Their standard model has a diameter of 666 meters, but a customer needs a larger tank whose capacity is 2.52.52, point, 5 times the volume of the standard model.
Sanjay wants to make a smaller pyramid using the same mold, so he plans to fill the mold 2 cm from the top.
What is the approximate volume of this smaller pyramid?
Round to the nearest cubic centimeter.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
