Question

use Pythagoras rule to find the slant height of a cone which has a,a base radius of 4cm and a height of 3 cm

Answer 1

Given

The base radius is 4cm, and the height is 3cm.

To find: The slant height using pythagoras theorem.

Step-by-step explanation:

It is given that,

The base radius is 4cm, and the height is 3cm.

That implies,

`\begin{gathered} Slant\text{ }height,l=√(h^2+r^2) \\ =√(3^2+4^2) \\ =√(9+16) \\ =√(25) \\ =5cm \end{gathered}`

Hence, the slant height is 5cm.I’ve completed answering the question.
