How do you find the area of a sector with degrees?

If the central angle measures 60 degrees, divide the 360 total degrees in the circle by 60. Multiply this by the measure of the corresponding arc to find the total circumference of the circle. Use the circumference to find the radius, then use the radius to find the area.

How many degrees is a sector of a circle?

Since a complete angle of a circle = 360°, the angle of each sector of the umbrella = 360/8 = 45° because the circle is divided into 8 equal sectors. Thus, the area of sector = (θ/360°) × π r.

What is the area of a 45 degree sector?

25.13 inch2
Answer: The area of the sector of the circle with a radius of 8 inches and an angle of 45 degrees is 25.13 inch2.

What is the perimeter of a sector of a circle whose central angle is 90 degree and radius is 7 cm?

The perimeter of a sector of a circle whose central angle is 90° and radius 7 cm is 25 cm.

What is the formula of area of minor sector?

Ans: If the central angle of the minor sector is \(θ\) then, the formula of the minor sector is \(=\frac{\theta}{360^{\circ}} \times \pi r^{2}\) where \(r\) is the radius of the circle.

What is the area of a 60 degree 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 sector angle?

Sector. A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. The angle formed by the two radii is called a central angle. A sector with a central angle less than 180° is called a minor sector. A sector with a central angle greater than 180° is called a major sector.

What is the area of a sector of a circle with radius 10 cm and angle radians?

Area of sector is 62.8 cm².

What is the perimeter of a sector whose central angle is 90 degree?

Answer: The answer is 25cm.
