Find the area of a circle with a diameter of 2 feet use 3.14 use pi Also please say all the. steps if you can
Answers
Given:
Diameter of a circle = 2 feet
To find:
The area of a circle.
Solution:
We know that, area of a circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Diameter of a circle = 2 feet
So, radius of the circle = [tex]\dfrac{2}{2}=1[/tex] feet
Putting r=1 and [tex]\pi=3.14[/tex] in the above formula, we get
[tex]A=(3.14)(1)^2[/tex]
[tex]A=(3.14)(1)[/tex]
[tex]A=3.14[/tex]
Therefore, the area of the circle is 3.14 sq. feet.
Find the equation of the line
Answers
Given:
The graph of a line.
To find:
The equation of the line.
Solution:
From the given graph it is clear that the line passes through the points (0,-2) and (4,1). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-2)=\dfrac{1-(-2)}{4-0}(x-0)[/tex]
[tex]y+2=\dfrac{1+2}{4}(x)[/tex]
Subtracting 2 from both sides, we get
[tex]y=\dfrac{3}{4}x-2[/tex]
Therefore, the equation of given line is [tex]y=\dfrac{3}{4}x-2[/tex].

Answer:
7 - 3 = 4
1 - (-12) = 13
9 + 11 = 20
7 - (-4) = 28
6 × (-3) = -18
(-8) × 9 = -72
5 + (-8) = -40
(-13) -2 = -26
(-13) + (-5) = 65
(-15) × -1 = 16
(-11) -12 = 132
(-9) × 3 = -27
14 + 8 = 22
60 ÷ (-4) = -15
(-4) + (-14) = -18
20 ÷ 5 = 4
(-12) + 8 = -96
6 + 11 = 17
(-14) × 7 = -98
(-12) - 15 = 180
12 × 13 = 156

Answer:
cosec <W = 68/60
Step-by-step explanation:
Using SOH CAH TOA identity
sin theta = opposite/hypotenuse
sin<W = XV/WV
Get WV using pythagoras theorem
WV² = 32²+60²
WV² = 1024 + 3600
WV² = 4624
WV = 68
sin<W =60/68
Since cosec <W = 1/sin<W
cosec <W = 68/60

As a part of their weather unit, Anoki’s science class took a hot air balloon ride. As they passed over a fenced field, the angle of depression of the closer side of the fence was 32°, and the angle of depression of the farther side of the fence was 27°. If the height of the balloon was 800 feet, estimate the width of the field. Round your answer to the nearest foot.

In a right triangle, one of the angles measures 29º. What is the measure of the
other angles in the triangle?
45° and 61°
90° and 42°
90° and 61°
90° and 51°
Answers
Answer:
90° and 61°
Step-by-step explanation:
Since it's a right angled triangle, I thought it was wrong since you said right angle.
180 - 29 = 151
There is always one right angle in a right angled triangle, which is 90°, so you just have to deduct 90° and 29° from 180° and you will find out the answer.
180 - 29 - 90 = 61°
