The name of a circle is the center. So P is the name of the circle and Point P is the actual center. We have, "circle P",

see explanation

Step-by-step explanation:

(1)

The arc length is equal to the central angle, thus

arc AB = 81°

(2)

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius and r = 9 )

   = 2π × 9 = 18π ≈ 56.5 cm ( to 1 dec. place )

(3)

Since BC is the diameter then  arc CB = 180°, thus

The complete circle = 360°, thus

arc BD = 360° - (180 + 65 )° = 360° - 245° = 115°

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
