Simply simplify the ratios/fractions into their simplest fraction form and divide the numerator by the denominator. If they are equal, they are in fact proportions, if not, they aren't

So, we have:
Remove absolute brackets
The answer is the last one with Amir as the 5 is the extra, and the 3 is multiplied by x or in this case days, and it is at least not equal.
Answer:
AREA= 198 mm
PERIMETER = 57mm
Step-by-step explanation:
1: to take out the perimeter , add all the sides i. e. 12+14+18+13=57
2: to take out the area use formula B*H i. e. base *height - area of a parallelogram
B=18
H=11
18*11=198
this is the area
HOPE IT HELPS !
The formula for the surface area of a cone is SA=(pi)(r^2)+(pi)(r)(l)
L is the slant height of the cone.
Because pi is in the answer choices, there is no need to multiply either by pi so the new formula becomes
SA=r^2+(r)(l)
Now you just plug in what you know
Sa=(8^2) + (8)(15)
Sa=64+120
Sa=184(pi)
*dont forget to put the pi back in since you took it out in the beginning of the equation*
Your answer is A.
Hope this helps :)
