Question

the slant height and base radius of a right circular cone are 17cm and 8cm what is the height

Answer 1

Hey friend..!! Here"s your answer
_________________________

Slant height (l) = 17 cm
Radius (r) = 8 cm

We know that,
${(l)}^{2} = ( {r)}^{2} + ( {h)}^{2} \\ \\ {(h)}^{2} = {(l)}^{2} - {(r)}^{2} \\ \\ ( {h)}^{2} = {17}^{2} - {8}^{2} \\ \\ {(h)}^{2} = 289 - 64 \\ \\ ( {h)}^{2} = 225 \\ \\ h = \sqrt{225} \\ \\ h = 15$

So that the height is 15 cm

Answer 2

Here
l=17 cm
r=8 cm
h=?
we know that
h^2=l^2-r^2
or, h^2=17^2-8^2
or, h^2=289-64
or, h^2 =225
or, h=√225
or, h=15
this is your answer
