To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the volume of a sphere and the formula for calculate the surface area of a sphere, which are:
[tex] V=\frac{4}{3} \pi r^{3} [/tex]
[tex] SA=4\pi r^{2} [/tex]
Where [tex] r [/tex] is the radius ([tex] r=0.8ft [/tex])
2. The volume is:
[tex] V=\frac{4}{3} \pi( 0.8ft)^{3} =2.1ft^{3} [/tex]
3. The surface are is:
[tex] SA=4\pi (0.8ft)^{2} =8.0ft^{2} [/tex]
The answer are: The volume is [tex] 2.1 ft^{3} [/tex] and the surface area is [tex] 8.0ft^{2} [/tex]
