The owner of the Rancho Los Feliz has 3000 yd of fencing with which to enclose a rectangular piece of grazing land along the straight portion of a river. Fencing is not required along the river, and the length of the fencing parallel to the river is to exceed the length of the fencing perpendicular to it by 1200 yd. Find the area of the enclosed land (in sq yd). Submit Answer sq yd -y y →|

An inverted circular cone has a radius of 10 cm and a height of 15 cm. When water level in the cone is x cm, the volume of the water is V cm³. Show that V = "x3. If the water is flowing out of the cone, find the approximate change in V, when x is 27 decreasing from 4 cm to 3.95 cm.

Use linear approximation to estimate the amount of paint in cubic centimeters needed to apply a coat of paint 0.01 cm thick to a hemispherical dome with a diameter of 6565 meters. Hints: Make sure you have the same units. Amount of paint is a difference in volume (here, of a hemisphere)!

The volume V of a fixed amount of a gas varies directly as the temperature T and inversely as the pressure P.

Kaminksy bronze sculpture is 5 feet in diameter, which is approximately 1.524 meters. if the sculpture was made of solid bronze, it's weight could be approximated using the density of bronze (d=7700 kg/m^3), the volume V in cubic meters, the mass, M, in kilograms and applying the formula d= m/v. Approximately, how many pounds would the sculpture weigh if it was made of solid bronze. (1 kg ≈ 2.205lb)
