The equation to find the area of a circle is pi x r2, let us just keep pi as pi, if the radius is 7, 72 is 49, so in terms of pi, the answer would be 49 pi, then one would just multiply 49 to whatever digit of pi you wanted to. answer is 153.86 :)
Area of any circle = pi*radius squared
The area is 154 cm2
The area of a circle is equal to pi*r2, where pi is the radius. In this case, the area is equal to pi*(7 feet)2, which is about 154 square feet.
A circle with a radius of 7 meters has an area of 153.94 square meters.
Using 3.14 as Pi the area of circle is: 153.86
3850m is the area of the a circle whose radius of 7meaters
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
Area of any circle = pi*radius squared
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
153.94 units2
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
A circle with a radius of 7 feet has an area of 153.94 square feet.
Using 3.14 as Pi the area of circle is: 153.86
The area is 154 cm2
