Question

Let a and b be two solid spheres such that the surface area of b is 300% higher than the surface area of
a. The volume of a is found to be k% lower than the volume of
b. The value of k must be___.

Answer 1

Answer:

hope you get your answer

Step-by-step explanation:

Let A and B be two solid spheres such that the surface area of B is 300% higher than the surface area of A. The volume of A is found to be k% lower than the volume of B. The value of k must be

----------------

300% more = 4 times the area.

Area is a function of r^2, so r = 2 times.

------

Volume is a function of r^3 --> B has 8 times the volume of A

A's volume is 7/8 less than B's --> 87.5% less volume

k = 87.5
