The radius of the sphere is half the diameter, or 6 feet; use the formula

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

Setting :

$V= $\frac{4}{3}$ \pi \cdot $6^{3}$ \approx904.8 $ft^{3}$$

A car dealership wants to fill a large spherical advertising ballon with helium. It can afford to buy 1,000 cubic yards of helium to fill this balloon. What is the greatest possible diameter of that balloon (nearest tenth of a yard)?

The volume of a sphere, given its radius, is

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

Set , solve for , and double that to get the diameter.

$1,000= $\frac{4\pi $r^{3}$$}{3}$

$r \approx \sqrt[3]{238.7} \approx 6.2$

The diameter is twice this, or 12.4 yards.

The volume enclosed by a sphere is given by the formula:

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

where is the radius of the sphere. The diameter of the balloon is 10 meters so the radius of the sphere would be $10\div 2=5$ meters. Now we can get:

$Volume=\frac{4}{3}$\pi $r^3$=\frac{4}{3}$\pi\times $5^3$=\frac{4}{3}$\times \pi \times 125\approx 523.6 $m^3$$

The volume of a sphere is:

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

Where is the radius of the sphere. We know the volume and can solve the formula for :

$Volume=\frac{4}{3}$\pi $r^3$=1000\Rightarrow $r^3$=\frac{3\times1000 }{4\pi}$\approx 238.85\Rightarrow r\approx 6.2$ inches

So we can get:

$Diameter=2r=2\times 6.2=12.4inches$

To find the volume of a sphere, use the following formula:

$\text{Volume}$=\frac{4}{3}$\pi\times $r^3$ , where is the radius of the sphere.

Now, because we are given the diameter of the sphere, divide that value in half to find the radius.

$r=10\div2=5$

Now, plug this value into the volume equation.

$\text{Volume}$=\frac{4}{3}$\pi\times $5^3$

$$\text{Volume}$=\frac{4}{3}$\pi\times 125$

$$\text{Volume}$=\frac{500}{3}$\pi=523.6$
