A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.
B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)
C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14
Answer:
12 dollars
Step-by-step explanation:
He spent 3/7 of 56
3/7*56 =24
Take the original amount and subtract what was spent
56-24 =32
He has 32 left
He spent 5/8 of that on a bat
5/8 *32 =20
Take the amount of money he had and subtract what was spent
32-20 = 12
He has 12 left
Answer:
cups
Step-by-step explanation:
Jacob mixes 
cup of yellow paint for every 
cup of blue paint to make green paint.
The ratio of yellow paint to blue paint = 
= 5:3
cup of blue paint = cup of yellow paint
1 cup of blue paint = ÷ cup of yellow paint
⇒ ÷
⇒
Hence, For 1 cup of blue paint needed cups of yellow paint.
