Amodel of a volcano has a height of 12 in., and a diameter of 12 in. what is the approximate volume of the model? use 3.14 to approximate pi, and express your final answer as a decimal. enter your answer in the box. in³

Hello there!

Volume formula for cone: V=1/3(π)(b)(h)

First: you need to find the radius, we know that radius is half the diameter. The diameter is 12, so the radius is 6.

Second: Now we substitute b for 6 and h for 12, since the height is 12. We will substitute π for 3.14.

Third: V=1/3(3.14)(6)(12). When you simplify: 1/3x3.14x6x12=452.16

Final answer=452.16in³

I hope this helps! :)

Step-by-step explanation:

In total, Lara walked 6+2=8 miles in 1.5+1=2.5 hours, and thus her average speed was 8/2.5=3.2 miles per hour.

Similarly, Tim walked 2+4+6=12 miles in 0.5+1.5+1.5=3.5 hours, and thus his average speed was 12/3.5=3.42 miles per hour.
