What is the area of a sector of a circle of radius 5 cm?

Given, radius = 5 cm and length = 3.5 cm. Therefore, Area of the sector of circle = 8.75 cm².

What is the area of a sector of a circle of radius 5 cm is formed by an arc of length 3.5 cm?

8.75 cm2
The area of a sector is given by the formula, lr2, where l is the length of an arc and r is the radius of the circle. Thus the area of the sector of length 3.5 cm formed by the circle of radius 5 cm is 8.75 cm2.

What is the area of a sector of a circle of radius 5 cm and its angle is 96 degrees?

The area of a circle of 5 cm radius = (22/7)*5*5 = 550/7 cm.. The area of a sector of the circle with an angle of 96 deg. = (96/360)*(550/7) = 20.95 sq cm. Answer.

What is the area of a sector of a circle with radius 5 cm and arc length of 10cm *?

Step-by-step explanation: Therefore, Area of the sector of circle = 8.75 cm².

What is area of sector of circle?

Area of a circle is given as π times the square of its radius length. So if a sector of any circle of radius r measures θ, area of the sector can be given by: Area of sector = θ360×πr2.

How do you find the area of a sector of a circle with the radius?

The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.

What is area of Arc?

Area of Sector Formula The area of a sector can be calculated using the following formulas, Area of a Sector of Circle = (θ/360º) × πr2, where, θ is the sector angle subtended by the arc at the center, in degrees, and ‘r’ is the radius of the circle.

How do you find the arc length and area of a sector?

To calculate arc length without radius, you need the central angle and the sector area:

1. Multiply the area by 2 and divide the result by the central angle in radians.
2. Find the square root of this division.
3. Multiply this root by the central angle again to get the arc length.

What is the area of sector?

Area of a Sector of Circle = (θ/360º) × πr2, 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 = 1/2 × r2θ, where, θ is the sector angle subtended by the arc at the center, in radians, and ‘r’ is the radius of the circle.

What is the area of the sector of a circle of radius 6 cm whose central angle is 30?

The area of sector of circle of radius = 6cm whose central angle is 30 degree is 9.42 cm sq.

How do you find the sector area of a circle?

Area of a Sector of Circle = (θ/360º) × πr2, where, θ is the angle subtended at the center, given in degrees, and ‘r’ is the radius of the circle. Area of a Sector of Circle = 1/2 × r2θ, where, θ is the angle subtended at the center, given in radians, and ‘r’ is the radius of the circle.
