The volume of a cone uses the following formula:

Our diameter is 20 feet, so divide this by 2 to find the radius:

We now have all of our values need to fill in the formula. Plug in these values:




The volume of the cone is
1780 cubic feet.
Answer:
100/100'000*5 = 5000 + base commission of 100'000 = 105'000
Step-by-step explanation:
Answer:

Step-by-step explanation:
We are given a triangle
whose sides are
a=12
b=8
c=13
Since, c is largest among them
So, angle C must be largest angle
we can find angle C
we can use law of cosine formula

now, we can plug values


now, we can find angle
we get

Answer:
One-half squared is one-fourth.
Step-by-step explanation:
When you divide fractions, you multiply the first term by the reciprocal of the second term. In this example, instead of multiplying 1/2 by 1/4, you now multiply 1/2 by 4. Therefore, one half is equal to 2 fourths.
208.81 square centimeters of aluminium are needed
<em><u>Solution:</u></em>
Given that,
Radius = 3.5 cm
Height = 6 cm
We have to find the square centimeters of aluminum needed
So we have to find the surface area of cylinder
<em><u>The surface area of cylinder is given by formula:</u></em>

Where "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the values we get,</u></em>

Thus 208.81 square centimeters of aluminium are needed
