Circle Sector Prob.

[Guest]

A circular sector has an area of 145.7cmsquared and a radius of 8.4cm. Calculate the perimeter of the sector to the nearest centimeter.

Any help would be appreciated. Thanks

Use the sector-area formula they gave you, plug in the given values for the area and the radius, and find the angle value.

Then plug the angle value and the given radius into the sector-arc formula they gave you. This will give you the length of the curvy part of the sector's perimeter.

Then add the two radius lines.
