Answer:
4pi in^2
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
π = pi
r = radius
h = height
Let me illustrate with an example
A cylinder has the following dimensions
r = radius = 20
h = height = 10
lateral area = 2 x π x 20 x 10 = 400π
If dimensions are reduced to one-fifth their original length, new dimensions are
r = radius = 20 x 1/5 = 4
h = height = 10 x 1/5 = 2
New lateral area = 2 x 4 x 2 x π = 16π
change in lateral area = 400π / 16π = 25
If dimensions are reduced by 1/5, lateral area would reduce by 25
100 pi / 25 = 4

Answer:
About 19.45%
Step-by-step explanation:
First set the fraction equal to x over 100 ———- (70/360)=(x/100)
cross multiply———- 70 * 100 = 7000 360 * x = 360x
solve for x —————- 7000=360x
7000/360= 19.44444444
Round ——- x=19.45
OR
Divide fraction ———— 70/360 = 0.1944444444
Next, convert to percentage by moving decimal 2 places to the right ——
019.44444444
Round ————- = 19.45
Answer:
(4.65 x 10)^3 = 100,544.625
Step-by-step explanation:
First, multiply 4.65 by 10
46.5
Now multiply this number by itself 3 times
46.5 x 46.5 = 2,162.25
2,162.25 x 46.5 = 100,544.625
So the answer is 100,544.625
Hope this helps :)
