Since line DB is perpendicular to line AC, then arc AB = arc BC
Thus, 14x - 3 = 7x + 18
Collecting like terms,
14x - 7x = 18 + 3
7x = 21
Dividing both sides by 7, we have


substituting x into the above equation,

Hence, angle the arc AC makes at the centre is 78 degrees.
Answer:
C.) True equation. X = all real numbers
Step-by-step explanation:
The volume of the ice cream is 72.03 in³.
<h3>What is the volume of the ice-cream?</h3>
The volume of the ice cream is the sum of the volume of the cone and the volume of the hemisphere.
volume of the cone = 1/3πr²h
1/3 x 22/7 x 2.5² x 6 = 39.29
Volume of the hemisphere = 2/3πr³
2/3 x 2.5³ x 22/7 = 32.74
The volume of the ice cream = 39.29 + 32.74 = 72.03 in³
