Question

Mendel’s team built a structure for a competition using wooden spheres and cylinders. The wood they used weighs 1 g for each 1.4 cm3. They used 4 spheres and 4 cylinders to build the base of the structure. Each sphere has a radius of 4.45 cm. Each cylinder has a radius of 3 cm. The base weighs 1700 g. What is the height of the cylinders? Use 3.14 to approximate pi and round the answer to the nearest whole number.
