Answer: The slant height of the cone is 65.6 m
Step-by-step explanation:
Given: The diameter of a cone = 10 m
Surface area of cone = 190.6 m²
To find: Slant height
Diameter of cone = 10 m
Therefore Radius of cone = 
As we know that surface area of a cone is given by

Where S.A. is surface area , r is the radius of cone and l is the slant height of the cone.
Let Slant height = l
So we have

Hence the slant height of the cone is 65.6 m

Hope This Helped! Good Luck!
The volume equals: Height * Width * Long
therefore the volume = 22.9*7.5*4.6 = 790 cubic meter.
11.82 which is closest to 12, would be the answer to ten times the quotient of 104 and 88.
