Mathematics

Delicious77 [7]4 years ago
5 0

Step-by-step explanation:

1. use the circumfrence equation which is 2pi*r

2 8 is the radius and r in the equation is the radius so we have 2pi*8= 16*pi

3. now find the arc of XY which is (16*pi)/(4) this equals 4pi

4. know that we know that one fourth around the circle is 4pi since arc XPY equals XY 3 times so arc XPY equals (4pi)*3 which equals to 12pi

5. so arc XPY equals 12pi

Answer:

The dimensions of a rectangular prism are 21 in. by 20 in. by 19 in.

To find:

The volume of the rectangular prism.

Solution:

Let the length, breadth and height are 21 in, 20 in and 19 in respectively.

-3(2x+4) = 3(x-6)<br> i need steps too
Bezzdna [24]

If you are looking to find the value of x then you have to use distributive property.

1st: multiply -3 by 2x and 4                -3(2x+4)

                                                             -6x -12

2nd: do the same thing on the other side which is multiply 3 by x and -6

                             3(x-6)

                               3x-18

3rd: Then you have  -6x-12=3x-18

                                        +12     +12

add 12 to each side so then you have -6x=3x-6

then divide by -6 on each side and the answer is x= 2/3
