Given ::
Height = 15CM
Diameter = 16CM = 16/2 = 8Cm
Radius = 8CM
Lateral Surface Area = ?
We know That
Lateral Surface Area = Pai × r √H² + R²
= 22/7×8√(15)²+(8)²
= 176/7√ 225 + 64
= 176/7 √ 289
= 176/7×17
= 2992/7
= 176CM2 Ans

Given:
Height of the cone = 15cm
Diameter of the cone = 16cm
To find:
LSA of the cone
Solution:
Since diameter is 16, thus radius will be -
r = d/2
r = 16/2
r = 8
Using the formula of LSA of Cone -
= πr√(r2 + h2)
Substituting the values -
= π × 8 √(8)² + (15)²
= π × 8 √ 64 + 225
= π × 8 √ 289
= π × 8 × 17
= 136π
Answer: The LSA of the cone is 136πcm²
