Given:-
• Let the base radius of cone be r
• height is 3 times the radius of. base then height= 3r
• volume = 134.75cubic.cm
To find:-
The base area of cone
Now
According to your question:-
We know that
- Now the radius of cone is 3.5cm
Height= 3×3.5 = 10.5cm
- Now we have to find the Area of base of cone

- Volume of Circular cone -
- Height = 3r
- Area of Circular cone base = ?
⇒Let the height of Circular cone - "h"
Let the radius of Circular cone - "r"
Now we find Radius through Volume of Circular Cone :
∵ Given that : h = 3r
∴
Therefore ,
We have now radius so we find easily area of base :
.........................Answer
If question in mention to find height so :
h = 3r
h = 3 × 3.5
h = 10.5 cm
