Answer:
Step-by-step explanation:
We know that the radius of cone r=7cm
and its height h=9cm
and the slant height of second cone =t cm
Then, according to the question.
Numerically: The lateral surface of second cone = volume of the first cone
πrl= 1/3 πr^2 h
π×7×l= 1/3 π×7 ^2 ×9
1= 1/3 × 7×3×9 / 7 = 21
