Question

if the radius and slant height of cone is 8 cm and 10 cm respectively,then its height is?​

Answer 1

Answer:

Let,

The slant height be l

Radius be r

h^2=l^2-r^2

h^2=10^2-8^2

h^2=100-64

h^2 =36

h=6

Answer 2

Given : –

• Radius of the cone = 8cm .
• Slant height of the cone = 10cm .

To Find : –

• Height of the cone ?

From Pythagoras theorem –

( slant height )² = ( height )² + ( radius )²

→ 10² = h² + 8²

→ h² = 10² - 8²

→ h² = 100 - 64

→ h² = 36

→ h = √36

→ h = 6

So, height of the cone is 6 cm .
