Answer:

$615.44\ in^2$

Step-by-step explanation:

The equation for the area of a circle is:

$A=\pi r^2$

Please note that "A" stands for "Area" and "r" stands for "radius".

We can substitute the given values into the equation:

$A=\pi r^2\\A=3.14*14^2\\A=3.14*196\\A=615.44\ in^2$

What is the m<br> 52<br> 40<br> 45<br> 54

lidiya [134]

Answer:

○ $\displaystyle 54°$

Step-by-step explanation:

Use the Triangular Interior Angles Theorem to figure this out:

180° = [3x]° + [2x]° + [5x]°

$\displaystyle \frac{180°}{10°} = \frac{[10x]°}{10°} \\ \\ 18 = x$

Plug this back into the <em>m</em>∠<em>L</em><em> </em>to get 54°.

I am joyous to assist you anytime.

Pentagon TEXAS has vertices at T(1, 8), E(3, 8), X(6, 2), A(3, 2), and S(1, 4). What is the area of Pentagon TEXAS?

Tamiku [17]

The area of the pentagon is 19 square units

The coordinates of the pentagon are given as:

$T = (1, 8)$

$E =(3, 8)$

$X =(6, 2)$

$A=(3, 2)$

$S = (1, 4)$

The area of the pentagon is then calculated using:

$Area = \frac 12|(x_1y_2+x_2y_3+x_3y_4+x_4y_5+x_5y_1) -(y_1x_2+y_2x_3+y_3x_4+y_4x_5+y_5x_1)|$

So, we have:

$Area = \frac 12|(1 \times 8 +3 \times 2+6\times2+3 \times 4 + 1 \times 8) -(8\times3+8\times6+2\times3+2\times1+4\times1)|$

Simplify the expressions in both brackets

$Area = \frac 12|46 -84|$

$Area = \frac 12|-38|$

Remove absolute bracket

$Area = \frac 12 \times 38$

$Area = 19$

Hence, the area of the pentagon is 19 square units
