Answer:
1.
circumference=diameter ×pi
=(29×2)× pi
=59×pi
area= pie × radius²
=pi×29²
=841pi
2.
circumference =pi×16.5
area=pi×8.25²
3.
153.94÷pi
radius=square root of 49.00062388
=7.000044563
times by 2
=14.00008913
4.
28.27÷pi
8.998620482=diameter
divide by two to find radius
4.499310241
then square
20.24379265
then times that by pi
=63.59775026
Let's define what as 'x'
3x = 75
Divide both sides by 3.
3x/3 = 75/3
x = 75/3
x = 25
Three times twenty five equals 75.
Your final answer is twenty five or 25.
For this case, the first thing you should know is the meaning of the acronym S.I.
