Final answer:
The circumference, surface area, and volume of Uranus can be calculated using the formulas for a sphere's circumference, surface area, and volume, respectively, by plugging in Uranus's radius of 2.56 × 10⁶ m.
Step-by-step explanation:
The distance around the equator of Uranus, which is also known as its circumference, can be calculated using the formula C = 2πr, where r is the radius of Uranus. Given that the radius of Uranus is 2.56 × 10⁶ m, we can calculate the circumference as C = 2 × π × 2.56 × 10⁶ m.
The surface area A of a planet like Uranus can be found with the formula A = 4πr². By plugging in the given radius, we get A = 4 × π × (2.56 × 10⁶ m)².
To calculate the volume V of Uranus, we use the formula for the volume of a sphere, V = (4/3)πr³, resulting in V = (4/3) × π × (2.56 × 10⁶ m)³.
