Lateral area of the cone = 15 π sq. cm

<u>Step-by-step explanation:</u>

Lateral area of the cone A = πr √(h²+ r²)

Here h = 4 cm and r = 3 cm

Plugin the values we will get the lateral area as,

A = π × 3 ×√(4² +3²)

= π × 3 ×√(16 +9)

= π × 3 ×√(25)

= π × 3 × 5

= 15 π sq. cm

I think what the teacher wants to express is that SI units are much more convenient to use than English units because the prefixes of the metric system will give you an idea on the conversion factor. Unlike English units, like ft to yard, there is no prefix to help you. You have to know the fact that 1 yard is equal to 3 feet.
