Find the surface area of a square pyramid with a length of 5 cm and a slant height of 8cm.


find the volume of a cone with a radius of 5 ft and a height of 12 ft.

Verified Answer :

area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 5 8 = 20 cm^2 and there are 4 sides
So the surface area  of while pyramid = 4 20 + 25 = 105 cm^2

Volume of the cone = (1/3) pi r^2 h
  = (1/3) pi 5^2 * 8
  =  209.44  ft^2
