Answer:
36
3
5
12
Step-by-step explanation:
The circumfrence of a circle is as follows
2πr
For this question π=3.14
So we have
113.04=2πr
solve for r
r= 18
which means that diameter is 36
Just do the same thing with the other questions
18.84=2πr
r=3
31.4=2πr
r=5
37.68=2πr
r=6 which means that the diamater is 12

Help? 11 3/4 is the quotient of a number y and 6 1/4
Answer:
y divided by 6 1/4 = 11 3/4
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
y divided by 25/4 = 47/4
Next, multiply both sides by 25/4:
y divided by 25/4 x 25/4 = 47/4 x 25/4
The 25/4's on the left side of the equation cancel each other out, leaving you with:
y = 47/4 x 25/4
Multiply 47 x 25 and keep the same denominator:
y = 1,175/4
Divide and:
y = 293 3/4
If 72 = 12x, what does x equal?
Answer:
x=6
Step-by-step explanation:
So, x is our unknown variable. An so you have to ask yourself, what times 12= 72? The answer would be 6, because 12x6=72
The proper way to do it, would be to divide 12/12 so you isolate the variable, and what you do to one side, you do to the other, so divide 72 by 12 and you get 6! Hope this helps!
