Answer:
180 degrees
Step-by-step explanation:
because i said so
L = w+22
2(l+w) = 4040
2(w+22+w) = 4040
2w + 22 = 4040/2 = 2020
2w = 2020-22 = 1998
w = 999ft
l = w+22 = 999+22 = 1021ft
w = 999 ft
Lets use 1 to solve this problem because it is easiest to show.
Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).
Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)
Therefore the page had a 9% reduction from its original size or is 91% of its original size.
Hey there :) You'll have to use the formula of cylinder to get your answer :
Surface area of cylinder : 2(pi)(r^2) + 2(pi)(r)(h)
pi = 22.7 or 22/7
r (radius of cylinder) = 8 mm
h = height of cylinder = 20mm
●Hence, just substitute your answer in the given formula and also don't forget to check whether the answer required needs to be in mm or cm.
Hope it helps :)
