1. Find the weight of the snowball 4 ft. in diameter if wet compact snow of which this ball is made weighs 30 lb, per cu. ft. 2. A spherical balloon is inflated so that its diameter is 40 ft. Find the surface area in the balloon's covering and the volume of the gas. 3. The altitude of the torrid zone is 3200 miles. Find its area, assuming the earth to be sphere with radius of 3960 miles. 4. A top consists of spherical segment and a cone (as shown in the figure). If the altitude of the segment is 1 inch, the radius of the common base is 3 inches, and the altitude of the cone is 6 inches. Compute the following: a. The total surface area of the top b. The volume of the top
