Find the area of the shaded sector of the circle

sweet-ann [11.9K]

Answer:

119.78 square m.

Step-by-step explanation:

$d = 28 \: m \implies \: r = 14 \: m \\ central \: \angle \:( \theta) \\ = 180 \:degree - 110 \degree \\ = 70 \degree \\ \\ area \: of \: sector \\ = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{70 \degree}{360 \degree} \times \frac{22}{7} \times {14}^{2} \\ \\ = \frac{7}{36} \times \frac{22}{7} \times 196 \\ \\ = \frac{7}{36} \times \frac{22}{1} \times 28 \\ \\ = \frac{7}{9} \times 22 \times 7 \\ \\ = \frac{1078}{9} \\ \\ = 119.777778 \\ \\ = 119.78 \: {m}^{2} \\$

URGENT, will reward brainliest. Determine the equation of the graph and select the correct answer below.

PilotLPTM [1.2K]

In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:

$y = a(x - h)^2 + k$

$a$ is a constant which helps to determine whether the parabola opens up or down. If $a < 0$ , then the parabola opens downward and if $a > 0$ , the parabola opens upwards
$(h, k)$ is the vertex of the parabola

By looking at the graph, we can first see that the graph opens downwards, meaning that $a < 0$ . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.

The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:

$y = -(x + 1)^2 + 3$

The answer is a, $-(x + 1)^2 + 3$ .
