Area of a circle = Pi * radius2
The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.
the area of the circle is increased by 400%
Area of a circle = pi*radius2
Divide the circumference by 2*pi which then will give you the radius and use pi*radius2 to find the area of the circle
If circ is 8pi the radius must be 4 so area is 16pi
2*pi*radius or pi*diameter
It is area
Approx 2011 acres.
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
The area of a circle with a radius of 15 cm is: 706.9 cm2
The area of the circle: pi*15*15 = 225*pi square measurements
The circle's area is 176.71 square feet.
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
The area is 176.714 units2
