Two cones have a radius of 2 cm. the height of one cone is 8 cm. the other cone is 1/4 of that height. which of these statements is not true?

Out of given option only option (d) is wrong.

The volume of the smaller cone cannot be determined because its height is unknown.

Step-by-step explanation:

Given two cones with radius 2 cm.

The height of one cone is 8 cm an the height of other cone is of the height of first cone.

Height of second cone = of the height of first cone.

                                     =

Volume of  cone =

Thus, Volume of smaller cone =

                              =

                               =

Thus, out of given option only option (d) is wrong.

The volume of the smaller cone cannot be determined because its height is unknown.

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
