What is the area of a sector with a central angle of 160 degrees and a diameter of 5.8 m? Round the answer to the nearest tenth.

Question

anonymous · Answer

first you gotta find the area of the circle

mathstudent55 · Answer

Do you know how to find the area of a circle?

anonymous · Answer

A=pi(r^2)

anonymous · Answer

this area is for all 360.
hene for unit angle at the centre
the area must be pi(r^2) /360  
thus for 160 as central angle

anonymous · Answer

you can have the sector are = 160 /360  *pi(r^2)
now you know the radius so you can ...

mathstudent55 · Answer

$\LARGE A_{sector} = \dfrac{n}{360^o} \pi r^2 $

where n is the degree measure of the sector, and r is the radius of the circle.
