A sphere and a cylinder have the same radius and height. The volume of the cylinder is 275 ft. hl
Which equation gives the volume of the sphere?
O V= (276)
V = 107

The perimeter of ? cde is 55 cm. a rhombus dmfn is inscribed in this triangle so that vertices m, f, and n lie on the sides cd , ce , and de respectively. find cd and de if cf=8 cm and ef=12 cm. the answer is not cd=20 and de=15. i have tried that one, it does not work.
