The formula for the area of a sector of a circle is given by ( A = \frac{\theta}{360} \times \pi r^2 ), where ( A ) is the area, ( \theta ) is the central angle in degrees, and ( r ) is the radius of the circle. If the angle is in radians, the formula simplifies to ( A = \frac{1}{2} r^2 \theta ). The length of the arc of the sector can be calculated using the formula ( L = \frac{\theta}{360} \times 2\pi r ) for degrees, or ( L = r\theta ) for radians.

If the arc length of a sector in the unit circle is 4.2 what is the measure of the angle of the sector?

In a unit circle, the radius is 1, so the arc length ( s ) of a sector can be calculated using the formula ( s = r\theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. Since the radius ( r = 1 ), the formula simplifies to ( s = \theta ). Therefore, if the arc length is 4.2, the measure of the angle of the sector is ( \theta = 4.2 ) radians.

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

To find the area of a sector when only the radius is given, you'll need to know the angle of the sector in either degrees or radians. The formula for the area of a sector is ( A = \frac{1}{2} r^2 \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. If the angle is not provided, the area cannot be determined solely with the radius.
