Find the height of cone, if its slant height is 34 cm and base diameter is 32 cm.OR About the author Sadie
Answer: Circular Cone Formulas in terms of radius r and height h: Slant height of a cone: s = √(r² + h²) 34=√(32/2)²+h² 34=√(16² +h²) on squaring both sides 1156=16²+h² 1156-256=h² h²=900 Step-by-step explanation: Reply
Given that : Slant height L = 34 cm. and Diameter = 32 cm. As we know that : [tex] {l}^{2} = {h}^{2} + {r}^{2} [/tex] where, l = slant height, h = height of the cone and r = radius of the base of the cone Now, [tex] = > {h}^{2} = {l}^{2} – {r}^{2} \\ \\ = > h = \sqrt{ {l}^{2} – {r}^{2} } \\ \\ = > h = \sqrt{ {(34)}^{2} – { (\frac{32}{2} )}^{2} } \\ \\ = > h = \sqrt{1156 – {(16)}^{2} } \\ \\ = > h = \sqrt{1156 – 256} \\ \\ = > h = \sqrt{900} = 30[/tex] So, the height of the cone will be 30 cm. ✔✔ _______________________________ Hope it helps ☺ Fóllòw Më ❤ Reply
Answer:
Circular Cone Formulas in terms of radius r and height h:
Slant height of a cone: s = √(r² + h²)
34=√(32/2)²+h²
34=√(16² +h²)
on squaring both sides
1156=16²+h²
1156-256=h²
h²=900
Step-by-step explanation:
Given that :
Slant height L = 34 cm. and Diameter = 32 cm.
As we know that :
[tex] {l}^{2} = {h}^{2} + {r}^{2} [/tex]
where, l = slant height, h = height of the cone and r = radius of the base of the cone
Now,
[tex] = > {h}^{2} = {l}^{2} – {r}^{2} \\ \\ = > h = \sqrt{ {l}^{2} – {r}^{2} } \\ \\ = > h = \sqrt{ {(34)}^{2} – { (\frac{32}{2} )}^{2} } \\ \\ = > h = \sqrt{1156 – {(16)}^{2} } \\ \\ = > h = \sqrt{1156 – 256} \\ \\ = > h = \sqrt{900} = 30[/tex]
So, the height of the cone will be 30 cm. ✔✔
