1: Exact volume of cone =  r^2 * h/ 3 =  15^2 * 9 / 3 =    225 * 9=  2025/3 = 675

2: Approximate volume of cone: pi* r^2 * h / 3 =  3.14 * 10^2 * 9/3 = 3.14 * 100* 9/3 =   3.14 x 900 / 3   = 2826/3 = 942 cm^3

3:  Asks for the same as problem above, but we have to divide the diameter by 2 to get the radius first 10/2=5 now we can solve. : 3.14 * 5^2 * 5/3 =   3.14 * 25 * 5/ 3 =  3.14 * 125 / 3  = 392.5/ 3 = 130.8 m^3

The exact volume does not use pi: so that is why the first one is 675
The Approximate used pi or 3.14.

What does A equal: 3(6a+12)=9
melisa1 [442]

Answer:

a = -3/2

Step-by-step explanation:

3(6a+12)=9

Divide each side by 3

3/3(6a+12)=9/3

6a+12 = 3

Subtract 12 from each side

6a+12-12 = 3-12

6a = -9

Divide by 6

6a/6 = -9/6

a = -3/2

How many unique triangles can be drawn with side lengths 8 in., 12 in., and 24 in.? Explain
Debora [2.8K]

By using the triangular inequality, we will see that no triangles can be made with these side lengths.

<h3>How many triangles can be made with these side lengths?</h3>

Remember that for any triangle with side lengths A, B, and C, the triangular inequality must be true.

This means that the sum of any two sides must be larger than the other side.

A + B > C

A + C > B

B + C > A.

For the given side lengths, we will have:

8 in + 12 in > 24 in

8in + 24 in > 12 in

12 in + 24 in > 8 in.

Now, notice that the first inequality is false. So the triangular inequality is not meet. Then we can't make a triangle with these side lengths.

So we can make 0 unique triangles with these side lengths.

The expressions p-0.15p can be can be used to calculate the final cost of an item that has a price of p and is discounted 15%. W
lora16 [44]

Answer:

The original cost is $19.55

Step-by-step explanation:

What we want to do here is calculate the final cost, given the original price

What we have to do here is to substitute the value of $23 for p

This we have as;

23-0.15(23)

= 23-3.45

= $19.55
