804.25 square units.
Area = pi*16*16 square units
256 Pi. The area of a circle is equal to the radius square multiply by pi
A circle with a radius of 16 cm has an area of 804.25 square cm.
4.
Area of any circle is: pi times radius squared
Area of a circle = π*r2 =π*16 =16*pi cm2
Area = pi * radius * radius radius = diameter / 2 radius = 16/2 = 8 Area = 64 * pi Area 201.062 inches2
The area of a circle is pi times the square of the radius: A = πr2. For a circle of radius 4, this is π x 42 = π x 16 = 50.265 units squared.A circle with a radius of 4 units has an area of 50.27 square units.
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16 inches, radius = 8 inches, and area = (pi) (8)2 = 201.062 square inches (rounded)
25/16
Area(A)/ Area(B) = pi*rA2/pi*rB2 = rA2/rB2 = 16/81
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
