Between 0° and 90° [1st quadrant] tan Ф  is always increasing, then positive:
tan (0°) = 0
tan (30°) = √(3)/3 = 0.577
tan(45°) = 1
tan (60°) = √3 = 1.732
tan (89°) = 57.28

We also know that tan (Ф) = tan (180° +Ф) [ 3rd quadrant]
The same logic as above applies

Identify the lateral area and surface area of a regular square pyramid with base edge length 11 cm and slant height 15 cm, round
Ann [662]

The surface area of the square pyramid is: 451 cm²

The lateral surface area of the square pyramid = 330 cm²

<h3>What is the Lateral Surface Area and Surface Area of a Square Pyramid?</h3>

Surface area = a² + 2al, where a is the base edge and l is the slant height.

Lateral Surface Area =  2al.

Given the following:

  • a = 11 cm
  • l = 15 cm

Surface area = a² + 2al = 11² + 2(11)(15)

Surface area = 451 cm²

Lateral Surface Area =  2al = 2(11)(15)

Lateral Surface Area = 330 cm²
