Answer:first one is 38.67 and the second one is 12
Step-by-step explanation:
Answer:
If we want our ratio to stay the same (3 to 5), we'll need to pair a set of 3 blue tacks with every set of 5 red tacks. In a group of 50, we can make 10 groups of 5 red tacks, so we'll also need 10 groups of 3 blue tacks, which gives us a total of 30 blue tacks
You will get r= 21/12 but you have to simplify to get R=7/4 or R=1.75
Answer:
Therefore,

Step-by-step explanation:
Let Assume Some Diameter of a Circle, to Solve it
Diameter = d = 14 inch ( say )
C =Circumference
Pi =constant = 3.14
To Find:
C = ?
Solution:
Formula for Circumference of a Circle is given as

Where,
C = Circumference
d = Diameter
Now Substitute d = 14 inches we get

This way we can find the circumference for any 'd' i.e Diameter
Therefore,
