Answer:
Correct volume = 100.48 cm³
Step-by-step explanation:
The formula for finding the volume of a cone is:
V = πr²(h/3)
r - Radius
h - Height
V - Volume
To find the correct volume of the cone, we just need to input the measurements into their respective places in the formula and solve. Your work should look similar to the following:
V = πr²(h/3)
V = π(4)²(6/3)
V = π(16)(6/3)
V = π(16)(2)
V = π(32)
V = 100.48 cm³
(You can use the work shown above to find Joan's mistake in her work.)

Okay, so on number one I have no idea. I keep getting 20 because 14 - (-3)2 = 14- (-6) which is really 14 + 6=20.
Number 2 is r+15=61
Number 3 I didn't get any of those answers because you have to solve what is in the parenthesis first so3*5= 15+1=16 then you multiply that by two giving you 16*2=32 and 42-32=10
Answer:
72km
Step-by-step explanation:
alex : tomos : annabelle = 2 : 3 : 4
if tomos drove 24km
tomos ratio is 3
so 3 --> 24
<em>1 --> 8 </em>
<u>total ratios --> 2 + 3 + 4 = 9</u>
so total journey is 9 --> 9 * 8 = 72km
