I'm not sure if i have the right in a circle with center o, central angle aob has a measure of (5pi)/4 radians. the area of the sector formed by central angle aob is what fraction of the circle?

The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Step-by-step explanation:

Let r be the radius of the circle having the center O,

⇒ The area of the circle =  square unit.

And, the central angle AOB =

 ( since, = 180° )

Hence, the area of sector AOB

square unit.

Now,

⇒ Area of sector AOB = 5/8 × Area of the circle.

Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
