This week I have learned how to find the slant height, volume and surface area of a cone. To find the slant height you will use the pythagereum theorem ( A^2 + B^2 = C^2) or 15^2 (height) plus 8^2 (radius) equals C^2 (slant height) 15^2 plus 8^2 = 287 then you will find the square root of 287 which is the slant height.
for volume the formula is 1/3 (area of base) x H or 1/3(pie8^2)15 which equals 1005.3 centimeters cubed which is the volume.
to find surface area the formula is: Pie R^2 + Pie R S or in this case Pie8^2+Pie8(17) to find the approximate value you can just put that into your calculator but to find the exact value you will have to o a little more work. Pie8^2+Pie8(17) = Pie64+Pie136 = Pie200
