Question

What is the radius of this cone?A. 4 cmB. 6 cmC. 12 cmD. 150.72 cm

Answer 1

Given: A cone with a diameter of 12 cm and height of 4 cm.

Required: To find the radius of the cone.

Explanation: Radius is half of the diameter, i.e.,

`r=(d)/(2)`

Here d=12 cm. Hence

`\begin{gathered} r=(12)/(2) \\ r=6\text{ cm} \end{gathered}`

Final Answer: Option B is correct.
