Question

A cone has a base radius of 3 cm and a slant height of 5 cm.

Answer 1

Answer:

h=4

Step-by-step explanation:

5²-3²=h²

h²=16

h=4cm

Answer 2

Answer:

I=4 (Slant height)

R=3 (Radius)

H=5 (slant height)

Step-by-step explanation:

Imagine inclination, peprendicular height and radius as a triangle, so this will have a 90 degrees angle and Pythagor theorem will imply to the calculations, as :

$a^{2}+b^{2}= c^{2}$

where Height is A , Radius is B, and Inclination is C we have:

$3^{2} +I^{2} = 5^{2}$

from above we have:

$I^{2} =25-9$

and

$\sqrt{I}=\sqrt{16} =4$
