What is the area to the nearest square foot of a two feet six inch and a quarter diameter circle?
Area A = pi * r^2
Radius r = 1/2D
Diameter D = 2r
(2' 6.25")=2r
12"=1' // convert everything to feet since that is the base unit of our answer
intuitively: 2 whole feet + a bit over half a foot = 2r,
therefore r should be about 1 and a quarter feet
(2/1)ft + (6.25/12)ft = 2r
2.5208333... ft = 2r
2.5208333.../2 = r
r = 1.26041666...
A = 3.14159 * (1.26041666...)^2
A = 4.9908917145408162765116711995003 ft^2
so, to the nearest square foot, the area of the circle is 5 sq ft
in square inches
2(12")+6.25" = 2r
24"+6.25" = 2r
30.25" = 2r
A= pi * (30.25/2)^2
A= pi * (15.125)^2
A= pi* 228.765625
A= 718.68840689387754381768065272805
Area ~ 718.75 inches^2
