✬ Slant Height = 13 cm ✬
✬ Curved Surface Area = 204.28 cm² ✬
Step-by-step explanation:
Given:
- Volume of right circular cone is 100π cm³
- Height of right circular cone is 12 cm
To Find:
- What is its slant height and curved surface area?
Solution: Let the radius of cone be r cm. We know that Volume of cone :-
★ Volume of cone = 1/3πr²h ★
A/q
100π cm³ = 1/3πr²12
100 π = πr²4
100 π\4π = r²
25 = r²
√25 = r
5 cm = r
Hence, The radius of cone is of 5 cm.
• Let the slant height of the cone be L cm. •
★ Slant height (L) = √(r² + h²) ★
L = √(5² + 12²)
L = √25 + 144
L = √169
L = 13 cm
