The sector of a circle has an area of 104 over 9 square inches and a central angle of 65 degrees what is the radius of the circl

Dmitriy789 [7]

If the area of the sector of the circle is 104/9 square inches. Then the radius of the sector of the circle is 4.51 inches.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The sector of a circle has an area of 104 over 9 square inches and a central angle of 65 degrees.

Then the radius of the sector of the circle will be

Area = (x/360) πr²

Then we have

104/9 = (65/360) πr²

r² = 20.37

r = 4.51 inches

If the area of the sector of the circle is 104/9 square inches. Then the radius of the sector of the circle is 4.51 inches.
