The space between the two spheres will be the volume of the larger sphere minus the volume of the smaller sphere. Given that the volume of any sphere is:
V=(4πr^3)/3 The space between to sphere of different radius and positioned about the same center is:
S=(4πR^3)/3-(4πr^3)/3 I used S=volume of space, R=larger radius and r=smaller radius...
S=(4π/3)(R^3-r^3), we are told that R=5 and r=4 so
S=(4π/3)(5^3-4^3)
S=(4π/3)(125-64)
S=(4π/3)(61)
S=244π/61
S=4π cm^3
S≈12.57 cm^3 (to nearest hundredth of a ml)

Complete question is;
Building an A - frame dog house. Your club has decided to build and sell dog houses for a fundraising project. You found this dog house a set of plans by searching the net.
side 1 = 45¼ in
side 2 = (Gusset plate)
5¾ in high
3⅓ in base
corner of side 2 = 2 inches thick
side 3 (floor plate)= 37¼ in
A customer has offered to pay extra if you will make one half the size called for in the plans. Take each of the 5 measures shown in the drawing and find half of the measure. Show your work to get full credit!
Answer:
new side 1 = 22⅝ in
For side 2:
New height = 2⅞
New base = 1⅔ in
New corner = 1 in
New side 3 = 18⅝ in
Step-by-step explanation:
We are told that a customer has offered to pay extra if you will make one half the size called for in the plans.
Thus, we will divide each number by 2
We are given side 1 = 45 1/4 in = 45.25 in
New side 1 = 45.25/2 = 22.625
Converting to fraction form: new side 1 = 22⅝ in
We are given side 2 = (Gusset plate)
Height = 5¾ in = 5.75 in
New height = 5.75/2 = =2.875
Converting to fraction:
New height = 2⅞
Base = 3⅓ in = 3.33 in
New base = 3.33/2 = 1.66
Converting to fraction:
New base = 1⅔ in
Corner of side 2 is 2 inches thick
New corner = 2/2 = 1 in
side 3 (floor plate) = 37¼ in = 37.25 in
New side 3 = 37.25/2 = 18.625
Converting to fraction:
New side 3 = 18⅝ in
