8/13 = 0.6153
y = cos-1(0.6153)
y = 52.0
I'm not totally sure if this is what you mean or if this is.
y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0
That would depend on how big or small the square is.
The lateral area is 117 square centimeters and the surface area is 292.72 square centimeters
<h3>How to determine the
lateral area?</h3>
The given parameters are:
- Base length (b) = 6
- Slant height (l) = 13
The lateral area is calculated using:
Lateral = 0.5 * (Perimeter of base) * Slant height
This gives
Lateral = 0.5 * (3 * 6) * 13
Evaluate
Lateral = 117
Hence, the lateral area is 117 square centimeters
<h3>How to determine the
surface area?</h3>
The surface area is calculated using:
Surface = l²√3
This gives
Surface = 13² * √3
Evaluate
Surface = 292.72
Hence, the surface area is 292.72 square centimeters
