I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.

Then add all the areas together.

Find the length of arc AD. Use 3.14 for .

Alexxandr [17]

Answer:

Length of arc AD = 15.7 cm

Step-by-step explanation:

Length of arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = Central angle subtended by the arc

r = radius of the circle

From the picture attached,

Central angle subtended by arc AD = 360° - (180° + 66.4°)

= 113.6°

Length of arc AD = $\frac{(113.6)}{360}(2\pi )(7.9)$

= $\frac{113.6}{360}(2)(3.14)(7.9)$

= 15.655 cm

≈ 15.7 cm

Length of arc AD = 15.7 cm

14+ 13y - 13y = 20y - 13y -21 (taking away the smallest y value from both sides)

14 = 7y - 21

14 + 21 = 7y - 21 +21 (+21 on both sides to remove -21 if we do -14 then we will have nothing on other side)

35 = 7y

35/7 = 7y/7 (dividing 7 on both sides)

5 = y

answer is 100% correct no doubts. hope it helped you.

Tony spent $50.35 on office supplies. He bought markers for $3.80 each and an organizer for $19.95. How many markers did tony bu

Mila [183]

Answer:

Step-by-step explanation:

Take the total, 50.35, and subtract 19.95:

50.35 - 19.95 = 30.40

Now divide 30.40 by 3.80:

(30.4)/(3.8) = 8

Therefore, Tony bought 8 markers.
