3. A cylindrical cooler has a diameter of 30 inches and a height of 24 inches. Runners in a marathon can use cone shaped cups to get a drink from the cooler. If the cups have a radius of 3 inches and a height of 4 inches, how many full cups would be able to be filled from the cooler?

When a substance has a density that is less than the density of water, it floats. A wooden sphere has a radius of 4 centimeters and a mass of 250 grams. Will the wooden sphere float? Use the fact that the density of water is 1 gram per cubic centimeter. Round answers to the nearest hundredth. A.  The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will float.   B.  The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will not float.   C.  The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will not float.   D.  The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will float.

As an art student, Joseph has a model of a rectangular prism sculpture, which is shown below. He wants to triple the length while keeping the other dimensions the same. How will the surface area of the larger prism compare to the original one? 5 cm 2 cm 0 2019 Glynlyon, Inc. O The surface area will triple the model rectangular prism. O The surface area will double the model rectangular prism. O The surface area will need to be roughly 2.6 times larger than the model rectangular prism. O The surface area will need to be roughly 3.6 times larger than the model rectangular prism. 3 cm

You can “unfold” a cube to make six squares, shaped like a cross. You can unfold a cylinder to make a rectangle and two circles. Is it possible to unfold a sphere? What would an unfolded sphere look like?
