A sphere has a volume of V=2304 in^3. Find its surface area.

The surface area of the sphere is:

Step-by-step explanation:

Recall the two following important formulas:

where R is the radius of the sphere.

Then, since we know the sphere's volume (2304 ), we can calculate the sphere's radius:

Now, knowing the radius, we can estimate the surface of the sphere using the other formula;

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
