The volume of a sphere is 1.3π x 10^9 cm³. Assume that Jupiter is a sphere. Find the surface area of Jupiter. Give your answer in standard form, correct to 3 significant figures.
1.87 x 10^10 cm²
1.87 x 10^9 cm²
1.57 x 10^10 cm²
1.57 x 10^9 cm²
설명
Volume = 4/3πr³. r = ∛(3V / 4π). Surface Area = 4πr². Therefore, Surface Area ≈ 1.87 × 10¹⁰ cm²
