2.45
DanJS
  • DanJS
now calculate \[C = 2*\pi*r\] \[A = \pi*r^2\] with those values approx
anonymous
  • anonymous
huh
DanJS
  • DanJS
use \[\pi~\approx~3.14\] r=2.45 and calculate C-circumference and A- Area for the circle

Circumference of a circle is the same as 2 times pi(3.14) times the radius C = 2*pi*r fill in the numbers and calculate

2*3.14*2.45=15.386 does this = the circumference
DanJS
  • DanJS
yes , i would keep 2 decimals for sig figures on it 26.39
DanJS
  • DanJS
15.39

  • anonymous
area would = 3.14*2.45^2=18.84785
anonymous
  • anonymous
what 26.39 for
DanJS
  • DanJS
mistype... yeah looks good
DanJS
  • DanJS
just remember the way to calculate those numbers, and what the radius and diameter are for the circle..
