a cone has a circular base of radius 5m and vertical height of 12m. Calculate the slanted height

Question

Radius of 5m and vertical height of 12m.

Answer 1

Given

Radius (r ) = 5m.

Vertical height (h ) = 12m.

Slanted height (l ) = √(r ² + h ²).

Substitute the values of r = 5 and h = 12 in l = √(r ² + h ²).

l = √(5² + 12²)

  = √(25 + 144)

  = √169

  = 13.

Therefore, slanted height of the cone is 13m.
