Answer:
9.38
Step-by-step explanation:
First let's start with what we know, we know the circumference and formula to get a circumference. (Formula: C= 2 π r) We also know how to find the circumference if we have the diameter. So what if we did it backwards? What if we divided? Let's try that, 29.48 ÷ π. Notice we don't put the radius because we don't know it yet. So when we do that on a calculator, we get 9.3885350 etc. Now we need to dived That by 2. That gives us 4.694267515 etc, but we can shorten that to 4.68. We're almost there! 4.68 is the RADIUS, not the diameter. so if you have the radius, you can easily get the diameter by mulitpling by 2. 4.68 x 2, is 9.38.
Answer:
C
Step-by-step explanation:
You can't divide 12 by 9, if you want a number with no decimals that is.
Answer
IS 2/4
Step-by-step explanation:
1/3 = 4/12 1/4 = 3/12 4/12+3/12= 6/12 = 2/4
4.221 is greater because of the .221
.022 see
Just equate each factor to zero and solve
