The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
A circle with radius 15mm will fit in a 30mm square. Find the intersection of the square's diagonals, that is the center of the circle.
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
radius = 60/2 = 30mm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
A circle with radius 15mm will fit in a 30mm square. Find the intersection of the square's diagonals, that is the center of the circle.
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
Area = pi*152 square mm
Area of the circle: pi*152 = 706.858 square mm to 3 decimal places
