Answer:

40π in²

Step-by-step explanation:

The area (A) of sector ODC is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{72}{360}

   = π × 10² × \frac{1}{5} = \frac{100\pi }{5} = 20π cm²

Sector OAB is congruent to sector ODC, thus

area of shaded regions = 2 × 20π = 40π in²

the variables x and y vary inversely with a constant variation of 7. Use the variation formula, k=xy, to find why when x=9
dolphi86 [110]

1.Make y the subject

k = xy

k/x = xy/x

y = k/x

2.Substitute

y = k/x

y = 7/9

y = 0.777......

y = 0.8 (Answer)

To confirm

k = xy

k = 9 × 0.8

k = 7.2

k = 7 (constant)

Hope it helps☺

<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.

cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft

</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41

Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.

(A) 0.10 feet
(B) 0.05 feet</span>
