I can’t figure this out, true or false?

False.

Step-by-step explanation:

Because 4 is a constant .Yeah

29.33π cm³  or 92.10 cm³

Step-by-step explanation:

To find the volume of a cone with height 5.5 and radius 4, we will simply use the formula;

volume of a cone = π r² h

h = 5.5  and r= 4, we will simply plug in these values into our formula

volume of a cone  =     ×  π   × (4)² (5.5)

                               =  ×π × 16 × 5.5

                                =88π   /  3

                                 =29.33π

volume of cone = 29.33π

But π= 3.14

plugging in π=3.14, we have;

volume of cone = 29.33(3.14)=29.10
