Given
The height of the conical heap = 24 cm
The radius of the heap is same as the radius of cylinder bucket.
Therefore the radios of the conical heap = 18 cm
In a cone
length² = height² + radius²
length² = 24² + 18²
length² = 576 + 324
length = √900 = 30 cm
The slant height of the conical heap = 30 cm
The height of the conical heap = 24 cm
The radius of the heap is same as the radius of cylinder bucket.
Therefore the radios of the conical heap = 18 cm
In a cone
length² = height² + radius²
length² = 24² + 18²
length² = 576 + 324
length = √900 = 30 cm
The slant height of the conical heap = 30 cm
