The space enclosed by the sector of a circle is called theareaof the sector. For example, a pizza slice is an example of a sector that represents afractionof a pizza. There are two types of sectors: minor and major sectors. A minor sector is a sector that is less than a semi-circle...
In geometry, we learn that a portion or a slice of a circle is known as a sector of a circle. If a circle has an area equal to {eq}\pi r^2 {/eq}, then the area of a sector of a circle subtending a central angle of {eq}\theta {/eq} is equal ...
Steps for Finding the Area of a Sector of a Circle with Exact Answers in Terms of Pi Step 1:Look at the given figure and identify the radius(r)and the value of the central angleθ. Step 2:Substitute the values identified in step 1 in the given formula to find t...
To find the Arc Length and Sector Area of a circle, you need the formulas and in this article, we review and explain these formulas.
A Sector Area Calculator is a tool that calculates the area of a sector of a circle. A sector is a portion of a circle enclosed between two radii and an arc. Enter Information Enter Information: Enter the central angle (in degrees): Enter the radius of the circle: Calculate ...
Step by step video, text & image solution for What is the area ("in cm"^(2)) of a sector of a circle, with central angle 75^(@), when the diameter of the circle is 9 cm ? (a)185pi//32 (b)135pi//16 (c)185pi//16 (d)135pi//32 by Maths experts to help you in doubt...
Area Bounded by Polar Curves Main Concept For polar curves of the form , the area bounded by the curve and the rays and can be calculated using an integral. Calculating the Area Bounded by the Curve The area of a sector of a circle with radius r and...
If a sector of a circle has an area of π units squared and the measure of its central angle (in degrees) is an integer, then the radius of the circle must be: ( ) A. π B. π^2 C. 6 D. 10 E. 36 相关知识点: 试题来源: 解析 C π=((360))π r^21=(360)r^2360=nr^2...
In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
Area of a Sector of a Circle:is a piece (or slice) of the total area of a circle. The two formulas that you will generally see for the area of a sector of a circle with radius, r, subtended by a central angle, {eq}\theta {/eq}: ...
