The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
124
Radius of circle is the square root of 154/pi = 7 units rounded
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
The area of a circle whose diameter is 12 inches is: 113.1 square inches.
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm

The diameter of a circle whose area is 200.96 is: 16
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
pi*25 = 78.5.
A = 804 square feet.
64pi (miles square)
Oh, dude, like, the area of a circle is π times the radius squared, right? So, if the diameter is 200 m, the radius is half of that, which is 100 m. Just plug that into the formula, and you get an area of 31,415.93 square meters. Easy peasy, lemon squeezy.
The area of a circle whose diameter is 6 mm is: 28.27 mm2
