The formula for an area of a circle is the greek symbol "pi" times the radius squared.
A = π * r2
r = radius
π = 3.14
Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).

What is the area of a circle when the diameter is 7 mm?
Diameter of a circle is pi times the square of its radius. For a circle having a diameter of 7 mm, area = pi (3.1416) x 3.5 mm x 3.5 mm = 38.5 square millimeters.
What is the area of circle with 7 yards?
Area of any circle = pi*radius squared
What is the area of a circle that has a radius of 7 cm?
The area is 154 cm2
What is the area of a circle with a radius of 7 feet?
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.
What is the area of a circle if the diameter was 14 meters?
A circle with a radius of 7 meters has an area of 153.94 square meters.
What is the area of a circle when the diameter is 7 mm?
Diameter of a circle is pi times the square of its radius. For a circle having a diameter of 7 mm, area = pi (3.1416) x 3.5 mm x 3.5 mm = 38.5 square millimeters.
What is the radius of a circle with a diameter of 7 mm?
3.5 mm
What is the area of a circle with a radius of 7 cm?
The area of a circle with a radius of 7 cm is: 153.9 cm2
What is the area of a circle with a radius of 7 meters?
3850m is the area of the a circle whose radius of 7meaters
What is the area of a circle with a radius of 7 centimeters?
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
What is the area of a circle if its circumference is 14π?
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).
What is the area of circle with 7 yards?
Area of any circle = pi*radius squared
What is the relationship between raidus and area?
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
How do you fine the area of a circle given the radius of the circle?
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 radius of a circle is multiplied by 7 Its area is times bigger than the original circle?
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
What is the area of a circle with a radius of 7?
153.94 units2
What is the area of a circle when the radius is 15?
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
