Question

) What would be the slant height of the cone, if the radius of its base is 5 cm and
its perpendicular height is 12 cm.​

Answer 1

Answer:

slant height=l=vr2 +h2

= 5^2+12^2 =v 25+144=v169=13

l =13cm

Answer 2

Answer:

13cm.

Step-by-step explanation:

r= 5cm and h= 12cm. l=?

since,

${l}^{2} = {r}^{2} + {h}^{2} \\ {l}^{2} = {5}^{2} + {12}^{2} = 25 + 144 = 169 \\ l = \sqrt{169} = 13cm.$
