so the pipe has an outer diameter of 6 inches so radius 3 inches an inner diameter of 6 inches - 2 x 1.25 so the inner diameter is 3.5 inches or radius 1.75 inches so find the area of the inner circle and then multiply by the height of 16 inches |dw:1439237745793:dw|

How do i find the area of the inner circle?
anonymous

Im retarded im sorry

multiply. cause its area
anonymous
  • anonymous
so what do i multiply
campbell_st
  • campbell_st
well the area of a circle is \[A = \pi r^2\] and you have your radius
campbell_st
  • campbell_st
so substitute and calculate the area... then multiply by the height

  • anonymous
ok sec
anonymous
  • anonymous
so A=3.14x1.75x 16?
campbell_st
  • campbell_st
well you need to square the inner radius...
anonymous
  • anonymous
so the inner radius is 9?
anonymous
  • anonymous
Im so incompetent
campbell_st
  • campbell_st
the area of the inner circle is \[A = \pi \times 1.75^2\] calculate the area then multiply by the height
anonymous
  • anonymous
I got 9.616 @campbell_st
campbell_st
  • campbell_st
that's ok for the area, now multiply by the height
anonymous
  • anonymous
