Question

3.4.2 quiz: why are cells so small? question 8 of 10 what is the ratio of surface area to volume for a sphere with the following measurements? surface area = 432 m² volume = 864 m³ a. 0.05 m⁻¹ b. 0.5 m⁻¹ c. 0.2 m⁻¹ d. 0.02 m⁻¹

Explanation:

Step1: Recall ratio formula

Ratio = $\frac{\text{Surface Area}}{\text{Volume}}$

Step2: Substitute given values

Ratio = $\frac{432\ m^{2}}{864\ m^{3}}$

Step3: Simplify the ratio

Ratio = $0.5\ m^{-1}$

Answer:

B. $0.5\ m^{-1}$
