Question

what is the ratio of surface area to volume for a sphere with the following measurements? surface area = 432 m2 volume = 864 m3 a. 0.5 m-1 b. 0.05 m-1 c. 0.02 m-1 d. 0.2 m-1

Answer 1

A

Step-by-step explanation:

just took the test lol

Answer 2

The answer is A. 0.5m⁻¹.

If we right the ratio in fraction form it will look like this:

`(432m^(2))/(864m^(3))`

Since they are similar terms we can divide them. When dividing exponents, you will subtract the denominator's exponent from the numerator and divide the numerical coefficients directly and you will be left with this fraction:


`(1m^(-1))/(2)}` or 0.5 m⁻¹
