Hey there! And welcome to Brainly.
Remember that the area of a circle is π*radius^2
Remember that there are 360<span>° in a circle.
</span>The angle of the unshaded part would be 360° minus the shaded part of 60<span>°.
</span>360°- 60° = 300<span>°
</span>Since the area of a circle is πr^2, and the section of the circle is 300°, or 300/360 = 5/6 or one full circle, the area of the unshaded region is
(5/6)π*radius^2
= (5/6)π*12^2
= 120π units^2

Answer:
9(1 +6)
Step-by-step explanation:
9 = 9 * 1
54 = 9 * 6
9 + 54 = (9*1 ) + (9*6) {9 is common in both terms}
= 9*(1 + 6)
Answer: Answer is D, a 55° angle
