Answer:
4
Step-by-step explanation:
I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.
Oooh fun!
Alright,
formula for a sphere is (4

r^3)3
4*pi*6^3=2714.34/3
904.78
Now you can do this 2 ways. First is that a cone is 1/3 of a sphere with the same radius so just take 904.78 and multiply it by 1/3 and then by 2 to get 2/3 of it or do this.
cone~ (6^2*pi*10)/3
376.99
and subtract
<span>904.78-376.99=527.79
</span>
<span>527.79^3 greater. Check my math. I could be wrong.</span>

Answer:
The area of the base is = 5.2 cm²
Step-by-step explanation:
<em>First, we need to know the formula to calculate volume:</em>

<em>if we change to our equations to the values we know:</em>

<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>

<em>We calculate the operation=</em>

<em>And the answer is 5.2 cm²</em>
<em>Let me know if you have any question :D</em>
