How do you figure the area of a circle if the radius is less than 1?

You still use the same formula.- Pi x r2
(for instance if it is 0.5 it would be Pi x 0.52)

What is the area if the circumference is 32 yd?
You didn't specify what figure you are talking about; the circumference or perimeter is different for different objects of the same size. For example, an elongated ellipse will have less area for the same circumference, as compared to a circle.Assuming a circle: First get the radius, as 32 / (2 * pi) = 5.0930. Next use the formula area = pi * r squared = pi * 5.0930 squared = 81.487 (square units).
What is the area for a circle with diameter of 10?
the formula for the area of a circle is A=pi x r2. r=the radius, and the radius is half of the diameter, which in this case, is 10. so the radius is 5. now you just plug it in. A=pi x 5 squared. now A=pi x 25 so the answer is 25pi. or you could do it to where you set pi as 3.14. then your answer would be 3.14x25 which is 78.5, so A=78.5 some teachers like it when you set pi to 3.14, and others like you to leave it just as pi. i personally like to leave pi as it is because its less work, but i don't know which one you needed...
How do you find the ratio of a circle inscribed a rhombus?
A rhombus is a flexible shape which can range from almost a square to a very narrow shape. A rhombus with sides of x cm can contain a circle with any radius less than x/2 cm. The information in the question is insufficient to determine the radius. And a ratio requires some characteristic of the inscribed circle to be compared to an analogous characteristic of another shape.
How do you graph x less than or equal to 3?
The graph is the set of all value of x that are less than or equal to 3, so you draw a line parallel to the number line, under the 3 and to the left of it (less than). Also, underneath the point three you draw a circle at the end o your line. Since it is less than or equal to you fill in that circle. Otherwise it would only be an outline circle.
How do you answer a inequalities on a number line?
x>2, you use an open circle above the #2 and shade to the right. If the equation was greater than or equal to 2, you would use a closed circle and shade to the right! Less than 2 would use the open circle to not include 2 and you would shade all numbers to the left of 2. Less than or equal to 2, solid circle which includes #2 and shade all #'s to the left of 2!
Is a circle with a area of 40 more less or same than a circle with a radius of 4?
In order to even discuss this question, we must assume that the unit of the '40' is the square of the unit of the '4'. -- The radius, diameter, and circumference of the circle with an area of 40 are each 10.794% shorter than the corresponding measurement in the circle with radius = 4 . -- Its area (40) is 20.423% less than the area of the circle with the radius of 4 .
Area of a circle with a 5 foot radius is it less than greaterr than or equal to 75.5 ft?
Greater than 75.5 square feet: a circle with a radius of 5 feet has an area of 78.54 square feet.
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
What is the area of a sector with a radius of 2cm and a arc of 18cm?
A sector with a radius of 2 cm can't have an arc of 18 cm. If the radius is 2 cm, then the entire circumference of the whole circle is a little less than 12.6 cm. Strange as it may seem, the area of that whole circle is a little less than 12.6 cm2 .
How do you find out if each point is on inside or outside of the circle?
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
What is the area of a circle when its radius is 4 inches less than its diameter?
Use the fact that the diameter is twice the radius. d = r - 4; replacing for d, 2r = r - 4

Definition of an interior of a circle?
the set of points whose distance from the center of the circle is less than that of the radius.
What is the interior of a circle?
The set points whose distance from the center of the circle that is less than the radius. A disk.
How is an apothem different from a radius?
An apothem is a line drawn perpendicular to a side of a regular polygon from the center of the polygon. A polygon is not a circle so it cannot have a radius. The radius of a circle is drawn from the center to any point in the circumference of the circle. You can draw a circle which encloses the regular polygon touching all vertices. The polygon is said to be inscribed in the circle. The apothem will be less than the radius because the radius is not perpendicular to any side, it can be drawn to a vertex but the apothem is perpendicular to a side, so it is shorter. Ex: draw a square with a circle which inscribes it. You can see that the apothem will be less than the radius.
How long is the radius of a 100 square mile circle centred on 9700 wallisville rd Houston tx 77013?
A circle with an area of 100 square miles has a radius of 5.6418 miles. Or, 5 miles, 1,129 yards, 1 foot, 8.5 inches - more or less.
