Question

Please I need help!!

Answer 1

Answer:

(b) 1272

Step-by-step explanation:

The volume of a cone is found using the formula V= $\pi r^{2} \frac{h}{3}$

So plug in each variable according to the image.

The radius is 9 and the height is 15, so plug those in and multiply out the answer. You were also told to use 3.14 for pi so plug that in aswell.

(3.14)(9*9)(15/3)

(3.14)(81)(5)

= 1271.7

= 1272

Answer 2

Answer:

the answer is 1272

V=πx9x9x15÷3

V=πx81x15÷3

V=πx1215÷3

V=3815.1÷3

Let me know if im right :)
