Another effective strategy for helping students improve their mathematics performance is related to solving word problems. More specifically, it involves teaching students how to identify word problem types based on a given problem’s underlying structure, or schema. Before learning about this strategy, however, it is helpful to understand why many students struggle with word problems in the first place.

Difficulty with Word Problems

Most students, especially those with mathematics difficulties and disabilities, have trouble solving word problems. This is in large part because word problems require students to:

Answer:

Slant Height = 20.1 km
Radius = 9 km
Lateral Area = 568.3 km²

Step-by-step explanation:

The slant height is read from the diagram as 20.1 km.

The radius is half the diameter, so is 9.0 km.

The lateral area is ...

A = πrs = π(9.0 km)(20.1 km) ≈ 568.3 km²

Desmos uses r for a special purpose, so we have used r₁ to signify the radius of the cone. The "round" function works only to round to an integer, so special effort must be used to get rounding to 1 decimal place.
