Why is it helpful to know the slant height of a pyramid to find its surface area?
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.
How do you find the slant height of a pyramid with a rectangular base?
If you make a line from the top of the pyramid to the center of the base, you have the height of the pyramid. This meets at the midsegment of a line going across the base. Since the height of a pyramid is perpendicular with the base, get this: the height, a line of 1/2 the length of the base, and the slant height form a right triangle. So, you can use the Pythagorean Theorem! For example, if the base length is 6 and the height of the pyramid is 4, then you can plug them into the Pythagorean Theorem (a squared + b squared = c squared, a and b being the legs of a right triangle and c being the hypotenuse). 1/2 the length of the base would be 6 divided by 2=3. 3 squared + 4 squared = slant height squared. 9+16=slant height squared. 25= slant height squared. Slant height=5 units. You're welcome!
How do you find lateral area of a regular square pyramid?
1/2(p)(sh) ~which means~ 1/2 x perimeter x slant height slant height= pathagorean theory= c squared= a squared+b squared
How do you find the perpendicular height of a square based pyramid?
To find the perpendicular height of a square pyramid, first compute for the volume of the pyramid. Then divide the volume by the area of the base to find pyramid's height.
How do you get the slant height of a triangle when you have a height of 5 and a radius of 4?
What do you mean by the radius of 4? Radius is used in circles. Do you mean that the breadth is 4? If so you can use Pythagoras's Theorem to find the 'slant height' (provided that it is a right-angle triangle) (slant height)2=52+42

How do you find the slant height of a cone if you have the lateral area and slant height?
Why do you need to FIND the slant height if you have the [lateral height and] slant height?
How do you find lateral area of a square pyramid?
You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.
How do you find the lateral area of a triangular pyramid with the perimeter and slant height?
LA=1/2ps
How do you find the slant height of a hexagonal pyramid give the height is 13.75 and the lateral edge is 15?
use formula bh/2. Substitute base with 15 and height with 13.75 and divide the product by two. That is the slant height.
How do you find slant height of a triangular pyramid?
Use the Pythagorean theorem: a^2 + b^2 = c^2 a = sqrt (c^2 - b^2) Where: a=the height (pyramid height from base to peak) b=the base length c = the hypotenuse (slant) length
