Answer:
201.06 square inches.
Step-by-step explanation:
The equation to use to find the Area of a circle is given as
πr²
Where r = radius of the circle
In the question, we are given the radius of the circle = 8 inches
Area of the circle = π × 8²
= 201.06 square inches.
Basically a proportion so it’d be 1in/300 mi = 3in/x mi
cross multiple that out and you get 300•3=x and then just solve for x. the answer should be 900 miles.
3.
a. 380 ÷ 38 = 10
b. 190 ÷ 38 = 5
c. 570 ÷ 38 = 15
d. use 10 times 38 = 380, 190 is half of 380 so half of 10 is 5, 570 is 380 + 190 so 10 + 5
4.
a. 670 ÷ 67 = 10
b. 603 ÷ 67 = 9
c. 737 ÷ 67 = 11
d. use 10 times 67 = 670, 603 is 670 - 67 so 10 - 1 = 9, 737 is 670 + 67 so 10 + 1 = 11
Challenge:
1062 - 279 = 783

783 - 261 = 522
522 ÷ 15 = 34 remainder 12
So she put 34 books in each box
Answer:
<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between, we can calculate for ∠A using the sine law:
</em>
<em>
</em>
<em>b / sin B = a / sin A
</em>
<em>
</em>
<em>2.45 / sin 60 = 2 / sin A
</em>
<em>
</em>
<em>sin A = 0.707
</em>
<em>
</em>
<em>A = 45˚
</em>
<em>
</em>
<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>
