Question

If the volume of a right circular cone of height 9 cm is 48 cm then find the diameter of
its base​

Answer 1

Answer:

Diameter=4.5cm

Step-by-step explanation:

Volume of cone=48cm³

⅓πr²h=48

⅓×22/7×r²×9=48

r²=48×3×7/22×1/9

r²=56/11

r²=5.1

r=√5.1

r=2.25cm

d=2r=2(2.25)=4.5cm

Therefore, the diameter of its base is 4.5cm.
