Answer:
C. 24pi cu ft.
Step-by-step explanation:
The equation to find the volume of a cone is v=pi r^2 h/3. So, just substitute the given information to the equation:
pi=3.14; r=6; h=2
V= pi 6^2 2/3 > V= pi(36) 2/3 > V=113.04 2/3 > V=75.36
Then you can go through all the answers and multiply them by 3.14.
6* 3.14=18.84; A is wrong
18* 3.14=56.52; B is wrong
24* 3.14=75.36; C is correct
48* 3.14=150.72; D is wrong
Now we know that the answer is C. 24pi cu ft.
Rent - 780
food - 900
medical - 450
clothes - 300
misc - 570
There are always two possible unit rates.
Either way, you just divide to find it.
(5 hours) / (216 miles) = 0.023 hours per mile .
(216 miles) / (5 hours) = 43.2 miles per hour .

Answer:
The polygon with the smallest perimeter is the megagon
The polygon with the largest perimeter is the triangle
Step-by-step explanation:
An equilateral triangle with area = 20 has
0.5× a²×sin60 = 20
a= 6.796
Hence, perimeter = 20.39
A square of area 20 has perimeter= 4×√20 = 17.9
A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05
Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases
Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.
