Sector of a Circle:A sector of a circle is some part of a circle that is the enclosed area between two radii and the corresponding circumference between the radii. An angle of {eq}360^{\circ} {/eq} at the center traces out the circumfe...
or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and the bigger the angle of the sector, the bigger slice of pie. Each side of the segment...
The radius of the given circle is5cm. The value of the central angleθis90∘. Step 2:Substitute the values identified in step 1 in the given formula to find the area of the sectorA=θ360∘πr2whereθis the central angle,ris the radius. We will not substitute ...
To find the area of a sector of a circle, use this formula:The area of a sector \(=πr^2 (\frac{θ}{360})\), \(r\) is the radius of the circle, and \(θ\) is the central angle of the sector.To find the arc of a sector of a circle, use this formula:Arc of a ...
Find the Arc Length and the Area of a Sector of a Circle Step 1:Note the radius of the circle and whether the central angle is in radians or degrees. Step 2:Use the appropriate formula to find either the arc length or area of a sector. ...
How to Find Arc Length Without the Radius? The arc length of a circle can be calculated without the radius using: Central angle and the sector area: Thesector areaformula is, (θ/360º) ×πr2, if θ is in degrees (or) (1/2) r2θ, if θ is in radians. ...
Percentages are a function of mathematics that enables you to compare two or more unequal things by expressing both as portions of 100. You can also express the number as a fraction or a decimal. For example, 10 percent is 10 out of 100, or 1/10 or .10. Calculate percentages by dividi...
The hand of a clock traces an arc of a circle as it passes through a rotation. In order to find the length of this arc we use this equation: {eq}s = r \theta \\ {/eq}Where s is the arc length, r is the radius and theta is the...
In Chapter 3, we discussed some of the top-level disk devices that the kernel makes available. In this chapter, we’ll discuss in detail how to work with disks on a Linux system. You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, ...
This is also the time to find out more about the type of clothing you are planning to produce and get to know all your competition. Talk to experienced professionals, find out what people are looking for and identify the gaps in the industry that you can fill. Competition is fierce and ...
