To find the radius of a cylindrical recycling container given its volume and height, we can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height.

We know:

  • \( V = 600,000 \) cm³
  • \( h = 76 \) cm

We can rearrange the formula to solve for the radius \( r \):

\[ r^2 = \frac{V}{\pi h} \]

Substituting in the known values:

\[ r^2 = \frac{600,000}{\pi \times 76} \]

Calculating \( \pi \times 76 \):

\[ \pi \times 76 \approx 238.76 \]

Now plug this into the equation:

\[ r^2 = \frac{600,000}{238.76} \]

Calculating \( \frac{600,000}{238.76} \):

\[ r^2 \approx 2510.84 \]

Next, we take the square root of both sides to find \( r \):

\[ r \approx \sqrt{2510.84} \approx 50.1 \]

Rounding to the nearest whole number, we find:

\[ r \approx 50 \text{ cm} \]

Thus, the radius of the container is approximately 50 cm.
