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.
radius = 32/(2*pi) inches
The area of a circle of radius 21 is 1386
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
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.
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
Area = pi*r2 Area = pi(3.2 cm)2 = 32 cm2 ======
The area of a circle if the radius is 9m 254.5m2
