Answer:
900
Step-by-step explanation
That would be 3 * 300 = 900
Diameter of cone = d = 4mm
So,
Radius of cone = r = 2mm
Slant Height = l = 6mm
Surface Area = A = ?
The formula for the surface area of cone is:
Using the values, we get:
mm²
Therefore, the surface area of the cone with diameter 4mm and slant height of 6mm will be 16π mm²
I’m sorry if this is wrong but I think 2.5?
