Answer:
1.
Circumference:
2*π*radius.
2*3.14*5
31.4
Circumference = 31.4
Surface area:
Substitute the values of the radius (r=5), the height (h=9), and an approximation for π(3.14) into the formula.
SA=2(3.14)(5)^2+2(3.14)(5)(9)
Simplify each term.
SA=157+282.6
Add 157 and 282.6 to get 439.6.
Surface area=439.6cm^2
Volume:
Substitute the values of the radius (r=5), the height (h=9), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.
V≈3.14⋅5^2⋅9
Raise 5 to the power of 2 to get 25.
V≈+3.14⋅25⋅9
Simplify
Volume = 706.5cm^3
2.
Circumference:
2*π*radius.
2*3.14*9
56.52
Circumference=56.52
Surface area:
Substitute the values of the radius (r=9), the height (h=24), and an approximation for π(3.14) into the formula.
SA=2(3.14)(9)^2+2(3.14)(9)(24)
Simplify each term.
SA=508.68+1356.48
Add 508.68 and 1356.48 to get 1865.16.
Surface area = 1865.16in^2
Volume:
Substitute the values of the radius (r=9), the height (h=24), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.
V≈3.14⋅9^2⋅24
Raise 9 to the power of 2 to get 81.
V≈+3.14⋅81⋅24
Multiply 3.14 by 81 to get 254.34.
V≈+254.34⋅24
Multiply 254.34 by 24 to get 6104.16.
V≈+6104.16in^3
3.
Circumference:
2*π*radius.
2*3.14*10
62.8
Circumference=62.8
Surface area:
Substitute the values of the radius (r=10), the height (h=15.5), and an approximation for π(3.14) into the formula.
SA=2(3.14)(10)^2+2(3.14)(10)(15.5)
Simplify each term.
SA=628+973.4
Add 628 and 973.4 to get 1601.4.
SA=1601.4
Surface area=1601.4cm^2
Volume:
Substitute the values of the radius (r=10), the height (h=15.5), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.
V≈3.14⋅10^2⋅15.5
Group coefficients together and exponents together to multiply numbers in scientific notation.
V≈+(3.14⋅15.5)(10^2)
Multiply 3.14 by 15.5 to get 48.67.
V≈+48.67⋅10^2
Write 48.67⋅10^2 in proper scientific notation.
V≈+4.867⋅10^3cm^3

2*3.14*24
Circumference=150.72
Surface area:
Substitute the values of the radius (r=24), the height (h=6), and an approximation for π(3.14) into the formula.
SA=2(3.14)(24)^2+2(3.14)(24)(6)
Simplify each term.
SA=3617.28+904.32
Add 3617.28 and 904.32 to get 4521.6.
SA=4521.6
Surface area=4521.6in^2

Okie dokie,
When converting a decimal, you use the place the decimal is in...
Let's review the places: tenths, hundredths, thousandths, etc.
You look at the last number to determine what place you're using!
-------------------
Now here's an example for the tenths place:
.5
it's in the tenths place, right? so put it over that number (with no decimal) over a 10.
(mobile) 5/10 or
Now, decide if you can simplify. You can! 5/10 simplifies down to 1/2.
is your answer!
--------
Example for the hundredths place:
.26
the last number is in the hundredths place, so put the number (without a decimal) over 100!
26/100 or
You can simplify this!
13/50 is your answer!
Calculators can also come in handy!
Good luck!

You must have learned "Order of Operations" or PEMDAS by now,
because that's what this whole question is talking about.
Look at the one in the first box:
32 ÷ 4² + 35 - 20 ÷ 5
You know how to do 4², and you know how to do 20÷5, and you know
how to do 4²+35, and you know how to do 35-20 .
But which one should you do first ? ! ?
pEmdas . . . do exponents. 4² = 16
Now you have 32÷16 + 35 - 20÷5
pemDas . . . do division. 32÷16 = 2
and 20÷5 = 4
Now you have 2 + 35 - 4
pemdAs . . . do addition: 2 + 35 = 37
Now you have 37 - 4
pendaS . . . Do subtraction: 37 - 4 = 33 .
That's the whole ugly thing in the first box. It's 33 .
Do the other two boxes the same way. Then you'll have a single number
for each box. Then just line up the three numbers in the order of their size.
This is all just one big PEMDAS exercise. If you do the operations in the
wrong order in one of the boxes, then you'll get the wrong number in that box.
