Which unit of measurement would be appropriate for the volume of a sphere with a radius of 2 meters

Semenov [28]

The volume of a sphere is found with the following formula:

$V = \frac{4}{3}\pi r^3$

The radius is raised to a power of 3. Since the radius is 2 <em>meters</em>, this means that the volume would be measured in cubic meters.

1/8 +c= 4/5 what does c equal

Ray Of Light [21]

Answer:

c=27/40 = 0.675

Step-by-step explanation:

the statement give us the expression:

1/8 +c= 4/5

we subtract the term "1/8" both sides:

we have:

1/8 -1/8+c= 4/5-1/8

c=4/5-1/8

c=(4*8)-(5*1)/(5*8)

c=(32-5)/(40)

c =27/40 = 0.675
