Answer:
About 733.04 feet
Step-by-step explanation:
Volume of Cone is given by the formula 
Where
- V is the volume
- r is the radius
- h is the height
Given height as 7 ft, and radius is 10 feet (Radius is half of diameter(20))
<em>Substituting into formula, we get:</em>
ft
Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
Since this is a right triangle, the Pythagorean Theorem can be used to find the missing side length. The Pythagorean Theorem is a² + b² = c², where c is the hypotenuse of the triangle.
The error is that the numbers were plugged into the theorem incorrectly - the hypotenuse is the side opposite the right angle (in this case, it is 8 ft). That means the c in a² + b² = c² should be substituted with 8, like so:
a² + b² = c²
6² + b² = 8²
Now that the numbers are substituted correctly, you may solve for the third side.
6² + b² = 8²
36 + b² = 64
b² = 28
b ≈ 5.29
Answer:
The third side length is approximately 5.3 feet.
Answer:
C
Step-by-step explanation:
A and B would be very expensive for 2 people, and D is too little, so C would be sensible! Hope this helps!
