Which two numbers on the number line has an absolute value of 3?
luda_lava [24]

Solution

             To    find   Which two numbers on the number line has  an

             absolute value of  3  

            Absolute   value   means    " how  far   a  number    is   from  

           zero "  .

           "3"    is    3    away   from   zero  .

           and    " -3 "   is  also   3    away   from  zero  .

           i.e

                    |  0  - 3  |   =   3

                    |  3 - 0 |  =  3

                    So ,  the  absolute   value  of   "3 "    is    3

                   similarly  , absolute  value  of  "3 "   is   3  .

                  Hence  , the  two  numbers   are   -3    and   3

Find the length of the missing angle
amm1812

Answer: x=7.21

Step-by-step explanation: This is a right triangle- remember the Pythagorean theorem: a² + b² = c². To find leg a, you'd use a = √(c² - b²) **leg a would be the side that is labeled with 12. To find leg b, you'd use b = √(c² - a²) *this is the equation we need. To find the hypotenuse, or <em>c</em>, you'd use c = √(a² + b²). This equation works for right triangles only.

Hope this helps :)

a cone has a volume of 6 cubic inches. what is the volume of a cylinder that the cone fits exactly inside of
ella [17]

Answer:

= 18 cubic inches

Step-by-step explanation:

The volume of a cone is given by the formula;

V = 1/3 × base area × height

While that of cylinder is given by the formula;

Volume = Base area × height

Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.

Therefore;

The cone has three times less volume compared to the cylinder.

Thus;

Volume of the cylinder = Volume of cone × 3

                                       = 6 In³ × 3

                                       <u>= 18 cubic inches</u>
