The area of any circle is (pi) x (radius)2 .The radius is 1/2 of the diameter.

32 x 32 x 3.14 = 3215.36 sqyds

As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.

The formula for the area of a circle is A = πr2 (π = Pi; r = radius)A = π x 322A = π x 1024A = 3.14 x 1024A = 3,215.36 un2

radius = 32/(2*pi) inches

Area of a circle = pi x radius2 The area of a circle with radius 3 cm = pi x 32 = 28.27433388 = 28.3 cm2 (1 decimal place)

Area = pi x (radius^2) so 3.14...(3^2) = 28.274333882308139146163790449516 cm²

Area = Пr2 = 3.14159 x 32 = 28.27

3215.36 square inchesArea of circle = π r2= 3.14 (32 inches)2= 3.14 (32 inches) (32 inches)= 3215.36 square inches

if the radius is a third then the area is a ninth 60.84 x 1/32 = 6.76 timmespi (if that's 'times pi' then) 6.76/pi = 2.15

radius = 32/(2*pi) inches

The formula for the area of a circle is A = πr2 (π = Pi; r = radius)A = π x 322A = π x 1024A = 3.14 x 1024A = 3,215.36 un2

Area = pi*r2 Area = pi(3.2 cm)2 = 32 cm2 ======
