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:
its 2 x I think u can defirantate
Answer:
my brain says (c) or (b) so, my answer would be (C)
Step-by-step explanation:
Y=3
Simplify
Distribute
Combine like terms
Add 2y to both sides
Add 2 to both sides
Divide by 3 , both sides.
If u want me to write the numbers and all just reply
Answer:
The answer is option A.
p = 0.7(rh + b)
Making h the subject
divide both sides by 0.7
we get
p/0.7 = rh + b
send b to the left side of the equation
p / 0.7 - b = rh
divide both sides by r
we get
( p / 0.7 - b) ÷ r = h
therefore h = ( p / 0.7 - b ) ÷ r
Hope this helps
