what's the radius of the circle?
gabbyalicorn
  • gabbyalicorn
umm 3.5
anonymous
  • anonymous
yep, so plug it into the formula and tell me what the area is
gabbyalicorn

anonymous
  • anonymous
no
anonymous

what is 3.5^2
gabbyalicorn
  • gabbyalicorn
12.25
anonymous
  • anonymous
correct. now multiply that by pi
gabbyalicorn
  • gabbyalicorn
38.465
anonymous
  • anonymous
yep, 38.5 works
anonymous
  • anonymous
ok, so that is the area of the metal
anonymous
  • anonymous
now we need to multiply that value by 3.25 to get the cost
gabbyalicorn
  • gabbyalicorn
okie so do we multiply 3.25 by π
anonymous
  • anonymous
no, multiply it by the area
gabbyalicorn
  • gabbyalicorn
which is -3- 3.5?
anonymous
  • anonymous
you just calculated the area
gabbyalicorn
  • gabbyalicorn
oh 38.5
anonymous
  • anonymous
38.5 x 3.25
gabbyalicorn
