Interactive practice questions

A soft drink can has a height of $13$13 cm and a radius of $3$3 cm. Find $L$L, the length of the longest straw that can fit into the can (so that the straw is not bent and fits entirely inside the can).

Give your answer rounded down to the nearest cm, to ensure it fits inside the can.

A cylindrical can is depicted with a vertical height of $13$13 units. Inside the cylinder, a line segment labeled 'L' extends diagonally, which is the length of the longest straw that can fit into the can, likely representing the slant height. At the top of the cylinder, the radius is marked as $3$3 units, as shown by a scale line.
