A circle with radius 3 has a sector with a central angle of 9/17 π radians .
What is the area of the sector?

Respuesta :

The area of sector is 7.48 square units

Solution:

Given that circle has radius 3

Central angle = [tex]\frac{9}{17} \pi[/tex] radians

To find: area of sector

The area of a sector of a circle is:

[tex]\text{Area of sector } = \frac{1}{2} r^2 \theta[/tex]

Where, "r" is the radius of circle and [tex]\theta[/tex] is the angle in radians

Substituting the values in formula,

[tex]\text{Area of sector } = \frac{1}{2} \times 3^2 \times \frac{9}{17 } \times \pi\\\\\text{Area of sector } = \frac{1}{2} \times 9 \times \frac{9}{17} \times 3.14\\\\\text{Area of sector } = 7.48[/tex]

Thus the area of sector is 7.48 square units
