The area of a circle with a radius of 15 cm is: 706.9 cm2
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
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)
Area of a circle is (pi) x (radius)Â². So how do you want to approximate pi: We could choose 22/7, for example. So (15 in)Â² = 225 inÂ², then multiply by 22/7 to get 4950/7 inÂ², or 707 1/7 inÂ².
Area of compass: 3.14*15*15 = 706.5 square mm
The area of a circle has the formula πr2 This means pi x radius squared. If the radius is 15. Square 15- 15x15. Multiply it by pi(3.14159265) Answer is 706.9mm2
The radius of a circle with an area of 706.50 square inches is: 15 inches.
706.86 square units.
Your answer will be 15 and for area its 28.26
diameter is 15 area of the circle is... 706.5 if im not mistaken
