Answer:

m<ABD = 56 degrees

Step-by-step explanation:

If a segment/ray/line bisects an angle, it divides it into 2 equal parts

Since BE bisects ABD, it will divide it into 2 equal parts, one of which is 28 degrees (given)

Now we can find the measure of ABD by doing 28*2=56

Vanyuwa [196]

Answer:

Step-by-step explanation:

Alright, lets get started.

Diameter of baseball is given as 3 inches.

Hence the radius of baseball will be : $\frac{3}{2}=1.5$

Hence the volume of baseball is : $\frac{4}{3}\pir^3$

Hence the volume of baseball is : $\frac{4}{3}\pi1.5^3$

Hence the volume of baseball is : 14.13 inches cube

Now, diameter of softball is given as 3.8 inches.

Hence the radius of softball will be : $\frac{3.8}{2}=1.9$

Hence the volume of baseball is : $\frac{4}{3}\pir^3$

Hence the volume of baseball is : $\frac{4}{3}\pi1.9^3$

Hence the volume of baseball is : 28.72 inches cube

Hence the difference of volumes will be: $28.72-14.13$

Hence the difference of volumes will be 14.59 or 14.6 inches cube

So the answer is 14.6 inches cube. : Answer
