Step-by-step explanation:
Total Surface Area of original cylinder
= (2×(22/7)×9)(9+24)
=18×22/7×33
=1,866.8
Total Surface Area of new cylinder
=(2×(22/7)×9/3)(9/3+24/3)
=(2×(22/7)×3)(3+8)
=6×22/7×11
=207.4
Change or Ratio of org. cylinder to new cylinder
=1,866.8/207.4
=9.0009
Answer:0.816
Step-by-step explanation:
Ape x
Answer:
D and A
Step-by-step explanation:
96 - 12 is 24, then you divide by 12. A and D are the same but D is Just A simplified
To solve this problem you must apply the proccedure shown below:
1. You have that the total area is obtained by applying the formula for calculate the area of a rectangle and multiply it by the four walls:
2. You know that each gallon of paint covers 100 ft², therefore, you can calculate the amount of gallons needed (which you can call 
), if you divide the total area of the walls by the area covered by each gallon:
The answer is: 12 gallons.
Let's call the weight of an ostrich o=180.
we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k
where k is the weight of a kiwi.
if we want to know k, we have to subtract 20 from both sides of the equation first:
160=4*k
and divide them by 4:
40=k
So a kiwi is 40 inches high.
