Answer:115 miles/hour
Step-by-step explanation: one mile equals to 5280 feet, so 607200 divided into 5280 is 115 and as your timing don’t change you can convert only the distance
Answer:
21/99 or 7/33
Step-by-step explanation:
x = 0.212121
Then we multiple the decimal and x by hundred.
100x = 21.212121
Then we subtract the 21.212121 by 0.212121.
100x = 21.212121 - 0.212121
But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.
100x - x = 21.212121 - 0.212121
You will have at the end is
99x = 21
Divide 99 on both side and you left with
21/99 or 7/33 simplified version
The surface area of a cylinder is given by:
A = 2 * pi * r * (r + h)
Where,
r: radio
h: height
Substituting values:
A = 2 * pi * 3 * (3 + 8)
Rewriting:
A = 2 * pi * 3 * (11)
A = 66pi square units
Answer:
A = 66pi square units
