Area of the base is πr² where r is the radius. The volume of a cone is ⅓ πr²h where h is the height.
So the volume is ⅓ π×9×10=30 π=94.25 cu in approximately.

Find the value of x if ∡A and ∡B are supplementary angles.

Elanso [62]

Answer:

$x = 30.5$

Step-by-step explanation:

Two angles are supplementary when they add up to 180°.

So we know that:

$C + D = 180$

Supplanting we get:

$(3x-44) + (5x-20) = 180$

We add up the X's.

$8x-44-20 = 180$

$8x-64 = 180$

Then we send 64 to the other side adding:

$8x = 180+64$

$8x = 244$

And then the 8 goes dividing:

$x = 244 : 8$

$x = 30.5$

What is a rational number?

jonny [76]

A rational number is: A number that can be written as a quotient of 2 integers, where the divisor is not 0.

Example: 2/5 , -6,

Because you can write any integer as a quotient with a denominator of 1, all integers are rational numbers,

Example: 5 = 5/1

Explain the role of the GCF in factoring a polynomial.

andreev551 [17]

The Greatest Common Factor (GCF) is the largest number that will be divided evenly into that number. For example, for 24, the GCF is 12. For a polynomial, the GCF is the largest polynomial<span> that will divide evenly into that polynomial.</span>
