The radius and height of a conical cup is in the ratio 3:4. If the volume of the cup is 2,376 cm3, which of these can be slant height of the cone, rounded off to the nearest whole number? |

Answer» VOLUME of cone V= 3 1
πr 2 h put h=4x and R=3x V= 3 1
×π×9x 2 ×4x=12πx 3 =96πcm 3
Thus, x 3 =8⇒x=2 h 2 +r 2
=5x=10cm |
