Step-by-step explanation:

Area of a circle: [tex]\pi r^{2}[/tex]  {r=radius}

[tex]\pi r^2=65.71cm2[/tex]

[tex]r^2=65.71/3.14[/tex] [tex](\pi =3.14)[/tex]

[tex]r^2=20.92[/tex]

[tex]r=\sqrt{20.92} =4.57cm[/tex]

[tex]r=4.57=5cm[/tex]

[tex]r=5cm[/tex]

Step-by-step explanation:

Answer:

16.97m

Step-by-step explanation:

We know that, all the 4 sides of a square are equal.

Given that,

Perimeter of the square is 48m

First, let us find the length of a side the square.

For that, let the length of a side be x.

Therefore,

x + x + x + x = 48

4x = 48

Divide both sides by 4.

x = 12 m

Now let us find the length of the diagonal using Pythagorean theorem.

For that let the length of the diagonal be y.

So,

12² + 12² = y²

144 + 144 = y²

288 = y²

√288 = y

16.97 m = y

Therefore,

The length of the diagonal is 16.97m

Answer:

Slope-intercept form:

[tex]y=\dfrac12x+\dfrac{13}2[/tex]

Standard form:

[tex]x-2y=-13[/tex]

Step-by-step explanation:

Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is the point)

Given:

Substituting these values into the point-slope formula:

[tex]\implies y-4=\dfrac12(x+5)[/tex]

[tex]\implies y-4=\dfrac12x+\dfrac52[/tex]

[tex]\implies y=\dfrac12x+\dfrac{13}2[/tex]

Slope-intercept form:

[tex]y=\dfrac12x+\dfrac{13}2[/tex]

Standard form:

[tex]x-2y=-13[/tex]

Answer:

[tex]\displaystyle y = -3x + 9[/tex]

Step-by-step explanation:

First, find the rate of change of the line:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}[/tex]

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

[tex]\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}[/tex]

m = - 4

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]

Substitute (-2,9) and (3,-11) into m = [tex]\frac{y_{2} -y_{1} }{x_{2} x_{1} }[/tex]

=  [tex]m=\frac{-11-9}{3-(-2)}[/tex]

m = -4

Answer:

Slope (m) = -4

Step-by-step explanation:

Given :-

Points (-2, 9) and (3, -11)

To Find :-

Slope (m)

Solving :-

m = y₂ - y₁ / x₂ - x₁

= -11 - 9 / 3 + 2

= -20 / 5

= -4

Solution :-

Slope (m) = -4

Answer:

87.9645943005 feet

Step-by-step explanation:

The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.

So, the radius is 14.

The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.

28 x pi = 87.9645943005

Answer:

Sum of interior angles of a triangle = 180°

Sine rule to find side lengths:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

----------------------------------------------------------------------

Question 1a

Given: A = 40°, B = 20°, a = 2

40° + 20° + C = 180°

⇒ C = 120°

[tex]\dfrac{2}{\sin 40}=\dfrac{b}{\sin 20}=\dfrac{c}{\sin 120}[/tex]

[tex]\implies b=\sin20 \cdot\dfrac{2}{\sin 40}=1.064177772...[/tex]

[tex]\implies c=\sin 120 \cdot \dfrac{2}{\sin 40}=2.694592711...[/tex]

----------------------------------------------------------------------

Question 2b

Given: A = 50°, C = 20°, a = 3

50° + 20° + B = 180°

⇒ B = 110°

[tex]\dfrac{3}{\sin 50}=\dfrac{b}{\sin 110}=\dfrac{c}{\sin 20}[/tex]

[tex]\implies b=\sin 110 \cdot\dfrac{3}{\sin 50}=3.680044791...[/tex]

[tex]\implies c=\sin 20 \cdot\dfrac{3}{\sin 50}=1.339426765...[/tex]

----------------------------------------------------------------------

Question 3c

Given: B = 70°, C = 10°, b = 5

70° + 10° + A = 180°

⇒ A = 100°

[tex]\dfrac{a}{\sin 100}=\dfrac{5}{\sin 70}=\dfrac{c}{\sin 10}[/tex]

[tex]\implies a=\sin 100 \cdot \dfrac{5}{\sin 70}=5.240052605...[/tex]

[tex]\implies c=\sin 10 \cdot \dfrac{5}{\sin 70}=0.9239626545...[/tex]

----------------------------------------------------------------------

Question 4d

Given: A = 70°, B = 60°, c = 4

70° + 60° + C = 180°

⇒ C = 50°

[tex]\dfrac{a}{\sin 70}=\dfrac{b}{\sin 60}=\dfrac{4}{\sin 50}[/tex]

[tex]\implies a=\sin 70 \cdot \dfrac{4}{\sin 50}=4.906726388...[/tex]

[tex]\implies b=\sin 60 \cdot \dfrac{4}{\sin 50}=4.522063499...[/tex]
