The phrase "area of circle" is correct and usable in written English.
You can use it in a variety of contexts when you are talking about the area of a circle. For example, "I am trying to calculate the area of circle with a radius of 3 units."
The aim of this study is to determine the learning difficulties in the perimeter and area of circle and perpendicular cylinder of the seventh year students in primary education, and to determine the effectiveness 4MAT teaching model overcoming learning difficulties.
Now an assumption of linear relative motion is usually applied in the calculation of collision probability and then the complex 3-dimensional problem can be reduced to a 2-dimensional integral of probability density function over the area of circle.
The findings of this study indicated that students had had learning difficulties about the perimeter and area of circle and perpendicular cylinder, and 4MAT based teaching was effective in overcoming these difficulties, whereas, traditional method was not effective in overcoming learning difficulties.
It is the ratio of the watershed area and the area of circle of watershed perimeter (P).
Miller (1953) defined a dimensionless circularity ratio (Rc) as the ratio of the basin area to the area of circle having the same perimeter as the basin.
It is the ratio of the watershed area to the area of circle having an equal perimeter as the perimeter of the watershed (P r ).
For example, he rigorously proved algorithms for determining the area of circles and the volume of pyramids by dissecting the regions into infinitely many pieces.
This total is then divided by the number of base cells and plotted against the area of circles with an increasing radius as in Martin (1980).
The width of the lines in Fig. 2 is proportional to the number of trials comparing each pair of treatments and the area of circles represents the cumulative number of patients for each intervention.
The width of the lines is proportional to the number of trials comparing each pair of treatments; the area of circles represents the cumulative number of patients for each intervention.
The nearest neighbor distance function p t) is identical to the probability of plotting a random point within the union area of circles whose radii are t and centers are the points.
