Area = pi x radius(squared)
A = (3.1416)(28 cm)^2
A = (3.1416)(784)
A = 2463 square centimeters
Radius = 10.997211381 units of measurement
Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
If i do understand what u are saying then the equation is area=pi(radius^2) In this case it is 28=3.14(r^2) the radius is equal to 3 so the diameter is about 6. If i do understand what u are saying then the equation is area=pi(radius^2) In this case it is 28=3.14(r^2) the radius is equal to 3 (approx.) so the diameter is about 6.
28"
The radius of a circle is half the length of its diameter. Therefore, to find the radius of a circle with a diameter of 28 cm, you would divide the diameter by 2. So, the radius of the circle would be 28 cm divided by 2, which equals 14 cm.
