Area of Circle formula in terms of DiameterThe diameter is double the radius, i.e., we can write diameter = 2 x radius. Therefore, the radius will be d/2. From the area of the circle 𝜋r2, putting the value of r in terms of d, we get,A = 𝜋 (d/2)2 = 𝜋/4 d2....
The sector of a circle is defined as the portion of a circle that is enclosed between its two radii and the arc adjoining them. It is considered as a portion of a circle with two radii and an arc. A circle is divided into two sectors, the minor sector and the major sector where the...

Answer to: The circle x^2 + (y+1)^2 = 4 has area 4 \pi . What is the area of the portion of the circle lying above the x-axis? By signing up,...
The Area of a Circle:A circle is a plane figure whose all the points on its boundary are at an equal distance from a fixed point. This point is the centre of the circle. The area of a circle is calculated as {eq}A = \pi r^2 {/eq}, where {eq}r {/eq} is the radius (the...
How to Find Area of a Segment The segment of a circle is the region between the chord and arc connecting the endpoints of the chord. A chord is a line segment that connects any two points on a circle. The segment would be the portion cut off of a sector if you sliced it at the ...
As we saw in question 6, this portion of the circle is called a "segment," and we find its area by taking the area of the sector minus the area of the triangle. The sector has area ((120)(360) )(π8^2)=(64π)3, and the triangle has area (12)(8√3)(4)=16√3, so ...
Arc of a Circle:An arc of a circle is referred to as a curve that is a part or portion of its circumference. Acute centralangleswill always produce minor arcs and small sectors. When the central angle formed by the two radii is 90o, the sector is called a quadrant because the total ...
