Find the volume of a cone with a base diameter of 8 yd and a height of 9 yd
8_murik_8 [283]

Answer:

V = 150.72 yd³

Step-by-step explanation:

To find the volume, we will need to use the formula  V = \frac{1}{3}bh

To find the base, we will need to use the volume of a circle, which is A = \pi r^{2}.

If the diameter is 8, the radius is half which is equivalent to 4. Put this into the equation:

A = π4²

A = 16π ≈ 50.24.

Now, use this in the Volume of a Pyramid formula:

V = 1/3 (50.24 ·9)

V = 150.72 yd³

a water ballon is to be randomly dropped along a 1 mile long line that stretches across a practice target zone. the target zones
Pavel [41]

Answer:

It seems like the question is not complete. So, I will asume that the complete question is: " A bomb is to be dropped along a mile-long line that stretches across a practice target.  The target center is at the midpoint of the line.  The target will be destroyed if the bomb falls within a tenth of a mile on either side of the center.  Find the Probability that the target is destroyed if the bomb falls randomly along the line."

Step-by-step explanation:

The total of possible cases is the length of the line = 1 mi ;

The favourable cases are the two lengths of 0.1 mi = 0.2 mi ;

Assuming the bomb has no bias for any point ,

the probability of favourable cases' occurrence is 0.2/1 = 0.2

Select the correct answer​
Paladinen [302]

Answer:

a)  We get \mathbf{A+B=x^2-2x+1}

So, Is the result of A+B is a polynomial:Yes

b) We get \mathbf{A-B=6x^3-7x^2+2x-1}

So, Is the result of A-B is a polynomial:Yes

c)  We get \mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}

So, Is the result of A.B is a polynomial:Yes

Step-by-step explanation:

We are giving the polynomial equations:

A= 3x^2(x-1)\\B=-3x^3+4x^2-2x+1

We need to find

a) A+B

A+B=3x^2(x-1)+(-3x^3+4x^2-2x+1)\\A+B=3x^3-3x^2-3x^3+4x^2-2x+1\\A+B=3x^3-3x^3-3x^2+4x^2-2x+1\\A+B=x^2-2x+1\\

So, we get \mathbf{A+B=x^2-2x+1}

So, Is the result of A+B is a polynomial:Yes

b) A-B

A-B=3x^2(x-1)-(-3x^3+4x^2-2x+1)\\A-B=3x^3-3x^2+3x^3-4x^2+2x-1\\A-B=3x^3+3x^3-3x^2-4x^2+2x-1\\A-B=6x^3-7x^2+2x-1\\

So, we get \mathbf{A-B=6x^3-7x^2+2x-1}

So, Is the result of A-B is a polynomial:Yes

c) A . B

A.B=3x^3(-3x^3+4x^2-2x+1)-3x^2(-3x^3+4x^2-2x+1)\\A.B=9x^6+12x^5-6x^4+3x^3+9x^5-12x^4+6x^3-3x^2\\A.B=9x^6+12x^5+9x^5-6x^4-12x^4+3x^3+6x^3-3x^2\\A.B=9x^6+21x^5-18x^4+9x^3-3x^2

So, we get \mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}

So, Is the result of A.B is a polynomial:Yes
