If the volume of a cone is 48π $$cm^3$$​ and the height is 10 cm . Find the radius of its base in nearest one decimal place.

Correct option is B

Given
Volume of the cone (V) = $$48\pi cm^3$$​​
Height of the cone (h) = 10 cm

Formula Used
Volume of a cone =$$\frac{1}{3}\pi r^2 h$$​​

Solution
Substitute the given values into the volume formula:
​$$48\pi = \frac{1}{3}\pi r^2 \times 10\\48 \times 3 = 10 r^2\\144 = 10 r^2\\r^2 = 14.4\\r = \sqrt{14.4} \approx 3.794 cm$$​​
Rounding to one decimal place, the radius is 3.8 cm.
Final Answer
So the correct answer is (b)
