To make it easier, aprox pi=3.14
area=pir^2
36=area
36=pir^2
divide both sides by pi
36/pi=r^2
36/3.14=r^2
11.464=r^2
square root both sides
3.39=r
circumfernce=2pir
r=3.39
circumfrence=2pi times 3.39
circumference=pi times 6.78
circumference=3.14 times 6.78
circumfernce=21.29
answer is
circumference=21.29 in
Answer:
Step-by-step explanation:
First we must find the missing number, for that we apply a simple rule of three:
3. 4
27 ------ x
x = 27 (4) / 3 = 36
Now we just do the sum:
27 + 36 = 63
Since it says only write a expression, you can do 45xM= ?/?
Hillary spent a total of 275 minutes studying for his Final.
What is unit conversion ?
When a unit conversion is performed, the same property is expressed in a different unit of measurement.
Here it is given that :
Hillary spent a total of 4 hours and 35 minutes studying for her Final
We known that :
1 hours equals 60 minutes
then,
4 hours and 35 minutes will be equals to = 4x60 + 35
= 240 + 35
= 275 minutes
Therefore, Hillary spent a total of 275 minutes studying for his Final.
