Step-by-step explanation:
closed circle on two and go the right
Answer: 1/20
Step-by-step explanation: = 1+8:36= 9 hours and 36 minutes
= 9+ 36/60= 9 3/5 hours
=48/5
Decrease per hour= 12/25 divided by 48/5
= 12/25 times 5/48= 1/20
Ans 1/20

Answer: Choice D</h3><h3>
m = n</h3><h3>
b = sqrt(pi)*a</h3>
=====================================================
Explanation:
Each circle has a radius of 'a'. So r = a.
The area of each circle is pi*r^2 = pi*a^2
The area of each square with side length b is b^2
The two stacks have the same volume only when the circle area is equal to the square area, so whenever pi*a^2 = b^2 is true.
Solving for b leads to b = sqrt(pi*a^2) = sqrt(pi)*a
The stacks must also be the same height for the volumes to be the same, so m = n as well.
