Answer:
1. R and Z 2. AC and AE
Step-by-step explanation:
When you have factors in shapes you must remember:
circumference and perimeter are in one unit measures
area is in squared units
volume is in cubed units
So, when the circumference of A is 4 times that of C there is a factor of 4.
Since we need to know the area the factor 4 will change to a factor of 4² since area is a squared unit.
The solution is 4²=16, the are of circle A is sixteen times the area of circle B.
To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.
In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2
Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.
Answer choice C is the best option.
I hope this helps! :)
If you change the fractions into decimals, 5/6=.83, 2/3=.67, 3/4=.75, you can see that 2/3 is the shortest
12 x 6 x 3 = 216
Volume = 216 cm cubed
216/0.03 = 7200
Answer = 7200 pencils
Hope it helped :)
