Answer:
9 cm
Step-by-step explanation:
Use the cone volume formula, V =
r²
Plug in the volume and radius, and solve for h, the height:
V =
r²
27
=
(3²)
27
= 9

3 = 
9 = h
So, the height of the cone is 9 cm
The more precise your length and width are, the more precise your area <span>measurement will be. Take this as example:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span><span>
Let's first round up:
width = 9.3 mm
length = 8 mm
Area = 9.3*8 = 74.4 mm
But if you are more precise with the width and length:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span>Area = 9.3045 * 8.023 = <span>74.6500035 mm
The more precise your length and width are, the more precise your area is. Also, as you can see t</span>he more precise your length and width are, the more your area will increase and will be more accurate.<span>

Steps To Solve:
~Find common denominators
4 2/7 = 4 10/35
2 1/5 = 2 7/35
~Turn into improper fractions
4 10/35 = 150/35
2 7/35 = 77/35
~Multiply
150/35 x 77/35 = 11,550/1,225
~Simplify
11,550/1,225 = 9 525/1,225 = 9 105/245 = 9 21/49 = 9 3/7

Hope This Helped! Good Luck!
Step-by-step explanation:
84 = 2(l+b)
L+b = 84 / 2
L+b = 42
There fore..
Length is 42 and breadth is 42 - 8
