The area of a circle with a radius of 7 cm is: 153.9 cm2
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).
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
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.
Area of a circle is (pi) x (radius)². So how do you want to approximate pi: We could choose 22/7, for example. So (15 in)² = 225 in², then multiply by 22/7 to get 4950/7 in², or 707 1/7 in².
The area of a circle with a radius of 7 cm is: 153.9 cm2
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
