. 2 360 360 oo oo mm Lr dπ π Area of a Sector of a Circle. π is of course the well-known mathematical. Arπ2 Circumference of a Circle.
Area of a sector. A spheres surface area can be calculated just by knowing its diameter or radius diameter 2 x radius. The surface area formula for a sphere is 4 x π x diameter 2 2 where diameter 2 is the radius of the sphere d 2 x r so another way to write it is 4 x π x radius 2Visual on the figure below.
The Area of a Segment is the area of a sector minus the triangular piece shown in light blue here. Do you mean how do you use this formula Lets try an example. L is the radius of the sector and the slant height of the cone.
Crd2π π Arc Length of a Circle. The formula is only correct if you use radians. Abh Area of a Circle.
2 360 o o m Ar π Area of a Segment of a Circle Area of sector Area of Triangle Area of a Regular Polygon. In a circle with radius r and centre at O let POQ θ in degrees be the angle of the sector. There is a lengthy reason but the result is a slight modification of the Sector formula.
Surface area of a sphere. Now by using the circumference of a circle formula c 2πr the above equation can be rewritten in terms of the radius of the cones base. Answer 1 of 12.
The region enclosed by two radii and an arc of a circle is called the sector of a circle. The area of a sector can be calculated using the following formulas Area of a Sector of Circle θ360º πr 2 where θ is the sector angle subtended by the arc at the center in degrees and r is the radius of the circle. Area of a Sector of Circle 12 r 2 θ where θ is the sector.
I hope that you know that 30 degrees is. Whats the area of sector with central angle 30 degrees and a radius of 3 cm. Adding the lateral area to the result for the area of the base of the cone we get A the total surface area of a right cone.
What are the formula for the area of a circle and the circumference of a circle. The formula for the area of circle pi r2 And the circumference of the circle 2pi r. The smaller area is known as the Minor Sector whereas the region having a greater area is known as Major Sector.
Area of a Trapezoid. 12 1 2 A bbh Area of a Parallelogram. In order to find the total space enclosed by the sector we use the area of a sector formula.
