A circular sector is the area between two radii of a circle and the arc between them.

The area is indeed given by

pi*r^2*(arc angle/360)

=pi*10.5^2(118/360)

=36.1375 pi cm^2

=113.529... cm^2

Therefore your answer is correct, to the first decimal place.

Perhaps you can check if the question specifies a different accuracy for the answer, or a different value of pi to be used.

Graph Ex+ 3y = 24<br> a.<br> b.<br> c.<br> d.

8090 [49]

Answer:

(b)

Step-by-step explanation:

Given

$8x + 3y = 24$

Required

The graph

First, make y the subject

$3y = 24 - 8x$

Divide through by 3

$y = 8 - \frac{8}{3}x$

Let x = 3

$y = 8 - \frac{8}{3}*3 = 8 - 8 = 0$

Let x = 6

$y = 8 - \frac{8}{3}*6 = 8 - 16 = -8$

So, we plot the graph through

$(3,0)$ and $(6,-8)$

Write an inequality to describe the situation.

nirvana33 [79]

Answer:

The inequality that describes the situation is:

$x \geq 8.75$

Step-by-step explanation:

The minimum hourly pay for working in Maryland is $8.75.

This means that the hourly pay for working, which is represented by variable x, has to be equal or greater than 8.75. So the inequality that describes the situation is:

$x \geq 8.75$
