If a radius of a circle is 9mm what is the diameter?
Diameter = 2 x radius = 18 mm .
What is the radius of a circle having a diameter of 1.06 meters Answer in mm?
It is: 1060/2 = 530 mm
What is the circumference of a 17 mm radius circle?
2 * pi * 17
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
Calculate the area of a circle with a radius of 450mm?
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
What is the area of a circle with a diameter of 13.2 mm?
The formula to calculate the area of a circle is A = πr^2, where r is the radius. Since the diameter is given, we can find the radius by dividing the diameter by 2. So, the radius would be 13.2 mm / 2 = 6.6 mm. Plugging in this value, the area of the circle is approximately 136.62 square millimeters.
What is the area of the circle if XY 5.4 mm?
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
What is the area of a circle if xy equals 5.4 mm?
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
Is the diameter of a circle is 26 mm then what is the radius?
13 mm. The radius of a circle is 1/2 of the diameter.
What is the radius of a circle with a circumference of 6.28 mm?
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
If the diameter of the circle is 30 mm then what is the radius of the circle?
The radius if the circle is half of its diameter and so 30/2 = 15 mm
What is the diameter of a circle with a area of 75 mm?
radius = square root of (75/pi) = 4.886025119 diameter = 2*radius = 9.772050238 or 10 mm to the nearest integer
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
What is area of a circle with radius of 2 cm?
A circle with a radius of 2 cm has an area of 12.57 square cm.
The size of 3mm circle?
Is that the radius or diameter? If it's the radius the area would be appx. 28.27 mm^2 and the circumference would be 18.85 mm If it's the diameter the area would be appx. 7.69 mm^2 and the circumference would be 9.425 mm. I may be off slightly, but I hope this helps enough.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
