Answer 1

Given:

Height of a cone 15 cm and diameter 8 cm

Required:

Find volume of cone.

Step-by-step explanation:

We know formula for

`\text{ Volume of cone =}(1)/(3)\pi r^2h`

We have diameter 8 cm. SO radius = 4 cm and height 15 cm

Now,

`\begin{gathered} V=(1)/(3)\pi r^2h \\ V=(1)/(3)\pi(4^2)(15) \end{gathered}`

Answer:

Except Jonah all are error.
