What is the exact volume of a sphere that has a radius of 7.5ft

Answers

Answer 1

Answer:

V=(4/3)(pi)r^3

r=7.5

V=(4/3)(pi)(7.5^3)
V=(4/3)(pi)(7.5^3)

V=(4/3)(pi)(421.875)

V=562.5pi ft^2

if you watnt to you can aprox pi=3.14

V=562.5*3.14

V=1766.25 ft^3

so answer is 562.5pi ft^3 or 1766.25 ft^3

Answer 2

Answer: since the equation for volume of a sphere is 4/3* π*r^3, you just plug in the radius. if you do this you get 4/3*421.875*π. multiply 4/3 and 421.875 and you get 562.5. now since it says EXACT, leave it in terms of pi; your answer would be 562.5π ft^3. if it said estimated or something along those lines then you would multiply by 3.14...... but since it says exact you leave pi alone.

To start the question, you must figure out how much money is 4% of 175000. You solve for that by multiplying .04 by 175000.

.04 * 175000 = 7000

Now, we have to find what percent 4725 is of 7000. First, let's convert that into a fraction: 4725/7000. To find the decimal, you divide the numerator by the denominator.

4725/7000 = .675

To turn that into a percent, you move the decimal two places to the right.

.675 turns into 67.5

Your teacher asked to round it up to the nearest tenth of a percent, but the number is short enough that we do not need to round. Your answer is 67.5%.
