Answer» A SPHERE ⚾ with maximum VOLUME can be cut from a solid hemisphere will be ONE whose Diameter is equal to the the RADIUS of the hemisphere let r be the radius of hemisphere Then radius of sphere = r / 2 volume of hemisphere. = 2 / 3π r^3 volume of sphere = 4 / 3π (r/2) ^ 3 RATIO = VOL.OF HEMI,SPH / VOL,OF, SPH = 2/3πr^3. / 4/3π((r/2))^3 = 4 Therefore. ratio = 4 : 1 Hope it helps!! Thank u |
