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
Approximate area of a 15 foot radius circle is a little more than 700 square feet.
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
706.86 square units.
For a circle Area is defined as: A = π(r)2 Where "A" is the area, "r" is your radius and π = 3.14 So for your circle: A = 3.14 x (15)2
