Answer:
A
Step-by-step explanation:
-1/2+c=31/4
-1/2+c+1/2=31/4+1/2
c=33/4
x 3
Step-by-step explanation:
Answer:

Step-by-step explanation:
Start by expanding the
into the
bracket using the distributive method:

Now, expand the result into the remaining bracket:

To get the answer we can use proportion
220 ----------------95.3%
x -------------------100%
Crossmultiply now
220*100%=95.3%*x
22000=95.3x /:95.3
22000:95.3=x
231=x - its the answer
C = 2 (pi) r
32 (pi) = c
32 (pi)= 2 (pi) r
r= 16
2r = d
d= 32
