Question

Find the slant height of the right circular cone if the base diameter of the right circular cone is 14 cm and the height is 24 cm.

11 cm
13 cm
28 cm
25 cm

hint Hint:

Slant height L = $square root of h squared plus r squared end root$
where h is height
r is radius of base of cone

The correct answer is: 25 cm

We have given the dimensions of a right circular cone
Base diameter = 14 cm
Radius, r = $14 over 2$ = 7 cm
Height, h = 24 cm $square root of 625$
Let us find the slant height
L = $square root of h squared plus r squared end root$
L = $square root of 24 squared plus 7 squared end root$
= $square root of 576 plus 49 end root$
= $square root of 625$
L = 25 cm
Therefore, the correct option is d) 25 cm.
