Question
Determine the slant height of a cone with a volume of
1,884 cm³ and a base radius of 15 cm. (Use π = 3.14)Solution
Volume of cone = (1/3) x π X radius2 X height So, (1/3) x 3.14 x 152 x height = 1,884 Or, 235.5 x height = 1,884 Or, height = 8 cm Now, slant height = √(radius2 + height2) = √(152 + 82) = √(225 + 64) = √289 = 17 cm
