# What is the area of sector of a circle with central angle 60 degree?

## What is the area of sector of a circle with central angle 60 degree?

32πcm2.

**What is the area of a sector of a circle that has a central angle of 60⁰ the circle has a radius of 10 cm?**

Area of the Major Sector is 261.7.

**Which of the following sector of a circle has a central angle of 180 degrees?**

semicircle

When the angle is 180 degrees, the sector is called a semicircle.

### What is the central angle of the sector?

The central angle is the angle subtended by an arc of a sector at the center of a circle. The central angle can be given in degrees or radians.

**What is the area of a 60 degree sector?**

That gives you the central angle of the sector. What is the area of a sector bounded by an arc of 60 degrees with a radius of 3 feet? As shown above, the formula is (60°/360°) π (3)² = (1/6)(3.14159)(9). The area will be expressed in square feet.

**What is the sector area of a sector created by circle with a radius of 4cm and a 40 degree central angle?**

Step-by-step explanation: So what I did was 50.27 times 40 which equals: 5.58555556, so I rounded it to 5.59 so that’s your answer!

## What is the perimeter of a sector?

The perimeter is the distance all around the outside of a shape. We can find the perimeter of a sector using what we know about finding the length of an arc. A sector is formed between two radii and an arc. To find the perimeter, we need to add these values together.

**Which sector has the greatest angle?**

major sector has the greater angle…

**Can a central angle be 180 degrees?**

A convex central angle, which is a central angle that measures less than 180 degrees and a reflex central angle, which is a central angle that measures more than 180 degrees and less than 360 degrees. These are both part of a complete circle.

### How do you find the perimeter of a major sector?

The perimeter of the sector of a circle is the length of two radii along with the arc that makes the sector. In the following diagram, a sector is shown in yellow colour. The perimeter should be calculated by doubling the radius and then adding it to the length of the arc.

**How is the area of a sector of a circle calculated?**

Then, the area of a sector of circle formula is calculated using the unitary method. For the given angle the area of a sector is represented by: The angle of the sector is 360°, area of the sector, i.e. the Whole circle = πr 2 Let the angle be 45 °. Therefore the circle will be divided into 8 parts, as per the given in the below figure;

**How to find the percentage of a sector from an angle?**

First, add together the degrees from the 3 sectors that include 9 or more hours of TV: 100 degrees, 85 degrees and 60 degrees. Take this sum, 245 degrees, and set-up a proportion: . A circle graph represents the demographics of a major US city.

## When is a sector of a circle called a quadrant?

Acute central angles will always produce minor arcs and small sectors. When the central angle formed by the two radii is 90° 90 °, the sector is called a quadrant (because the total circle comprises four quadrants, or fourths). When the two radii form a 180° 180 °, or half the circle, the sector is called a semicircle and has a major arc.

**How to calculate the arc length of a sector?**

r = C (2π) r = C ( 2 π) Once you know the radius, you have the lengths of two of the parts of the sector. You only need to know arc length or the central angle, in degrees or radians.
