Answer:
Step-by-step explanation:
GIVEN: Suppose you want to make a cylindrical pen for your cat to play in (with open top) and you want the volume to be cubic feet. Suppose the material for the side costs per square foot, and the material for the bottom costs per square foot.
TO FIND: What are the dimensions of the pen that minimize the cost of building it.
SOLUTION:
Let height and radius of pen be
Volume
total cost of building cylindrical pen
for minimizing cost , putting
Hence the radius and height of cylindrical pen are and respectively.
Answer:
A
Step-by-step explanation:
Step-by-step explanation:
<A + <B = 180
6x-35+ 3x+53=180
9x=162
x=18
<A= 6(18) -35
<A= 73°
