A solid shape is made by joining two cones. Each cone has the same radius.
One cone has slant height = 2 x radius
The other cone has slant height = 3 x radius
The total surface area of the shape is 135.2 cm?
Curved surface area of a cone = ar where r is the radius and / is the slant height
Work out the radius.
