I. ABCD is a square so ∡BCD=90°
|BC|²+|CD|² = |BD|²
8² + 8² = |BD|²
|BD|² = 8²·2
|BD| = √[8²·2]
|BD| = 8√2
II. Circular segment BCD is a quater of circle (because ∡BCD=90°)
R=8
So the lenght of arc BD:
Perimeter of the figure: The area of circular segment BCD:
III. The area of triangle BCD:
IV. The area of figure:
X< -4
You need to do inverse operations and add 12 to both sides.
Answer:
b
Step-by-step explanation:
Answer: <em>33 square feet</em>
Step-by-step explanation:
<em>First, let's take the area of the rectangle shown here which is 6ft long and 4ft wide</em>
<em>6x4=24</em>
<em>Now let's take the area of the square which is 3ft long and 3ft wide</em>
<em>3x3=9</em>
<em>Now add 24 and 9 for the total area</em>
<em>24+9=</em><em>33 square feet</em>
Given 736 hours, we are asked to find how many days are in it. This can be seen below.
Let x be the number of days in 736 hours. Since there are 24 hours in a day, we would have;
Thus,
Answer: 30.7
