If the number of square centimetire on the surface of a sphear is equal to the number of cubic centimetres in its volume what is the diameter of the sphere

The diameter of the sphere is 6 centimeters

Step-by-step explanation:

we know that

The surface area of a sphere is

The volume of the sphere is

Equate both formulas

Simplify

Remember that the diameter is two times the radius

so

therefore

The diameter of the sphere is 6 centimeters

$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)
