This is on a practice assessment, not for a grade therefore I need help solving this because I completely forgot what to do
Lesechka [4]

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

\begin{gathered} x=\frac{21}{7} \\ x=3 \end{gathered}\begin{gathered} \angle AC=\angle AOB+\angle BOC \\ \angle AC=14x-3+7x+18 \\  \end{gathered}

substituting x into the above equation,

\begin{gathered} \angle AC=14(3)-3+7(3)+18 \\ \angle AC=42-3+21+18 \\ \angle AC=78^0 \end{gathered}

Hence, angle the arc AC makes at the centre is 78 degrees.

Pankaj gets ice cream in a cone that is 6 inches tall and has a radius
Arisa [49]

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
