Answer:
Step-by-step explanation:
d = c/pi
so d = 62.8/pi
d = 62.8/pi or appr 19.99in
r = d/2
so r = 62.8/2pi or 31.4/pi appr 19.99/2

so

then

so
a = approximately 313.84
answer is rowan
35x plus 12
you cannot add them since they are not like terms
What do you mean??????????????
A = lw
525 = (25)(w)
525 = 25l
25 25
21 = w
Equal to 4.73 repeating, rounded is 4.7
