Answer

\(\boxed{\text{The radius of the sphere with a volume of 802 m³ is approximately 5.8 meters}}\)

Steps

Step 1 :Given the volume of the sphere, \(V = 802 \mathrm{~m}^{3}\)

Step 2 :Use the formula for the volume of a sphere, \(V = \frac{4}{3} \pi r^3\)

Step 3 :Rearrange the formula to isolate r: \(r^3 = \frac{3V}{4\pi}\)

Step 4 :Take the cube root of both sides to solve for r: \(r = \sqrt[3]{\frac{3V}{4\pi}}\)

Step 5 :Plug in the given volume (802 m³) and calculate the radius: \(r = \sqrt[3]{\frac{3(802)}{4\pi}}\)

Step 6 :Calculate the radius: \(r \approx 5.763618849184167\)

Step 7 :Round the radius to the nearest tenth of a meter: \(r \approx 5.8\)

Step 8 :\(\boxed{\text{The radius of the sphere with a volume of 802 m³ is approximately 5.8 meters}}\)
