Answer:
Explanation:
Let the diameter of base of right circular cone is 'd' cm.
Therefore, radius will be .
It's given that the volume is
And, height is 9 cm
But, Volume of cone is given by ,
Therefore, we have the relation,
Hence, diameter of the base is 8 cm

AnswEr:
- Diameter of the base = 8 Cm.
Given That:
- Height of the cone = 9 Cm
- Volume of cone = 48π Cm³
Need To Find:
- Diameter of the base = ?
ExPlanation:
Let, Radius of the cone = r Cm
Formula used here:
- Volume of cone = 1/3πr²h
Putting the values according to the given formula:

Now, again formula used here:
- Diameter = 2 × Radius
Putting the values according to the given formula:
➠ Daimeter = 2 × 4
➠ Diameter = 8 Cm
ThereFore:
- Diameter of the base = 8 Cm.
What is Radius?
- Radius is a line segment joining the centre of a circle to any point on the circle.
What is Diameter?
- Diameter is a line segment whose in points lie on the circle and which passes through the centre of the circle.
- Diameter = 2 × Radius
