Find the area of the composite shape

Mathematics
1 answer:
Alexxandr [17]3 years ago
8 0

Answer:

13.735 ft^{2}

Step-by-step explanation:

Area of a circle.

A=\pi r^{2}

r=d/2\\r=8/2\\r=4

A=\pi \times 4^{2}

A=16\pi

A \approx 50.2654824574

Area of a square.

A=s^{2}

A=8^{2}

A=64

Subtract the area of the square with the area of the circle.

64-50.2654824574

= 13.7345175426

I hope it helps.

Brainliest much appreciated.

How do you do this question?
Norma-Jean [14]

Answer:

Divergent

Step-by-step explanation:

an = 3 sin(2/n)

Choose bn = 3 (2/n).

Using Limit Comparison Test:

lim(n→∞) an / bn

= lim(n→∞) [3 sin(2/n)] / [3 (2/n)]

= lim(n→∞) [sin(2/n)] / (2/n)

= 1

The limit is greater than 0, and bn diverges, so an also diverges.

Reduce the following fraction: -36x^4y^4z^5/-12x^6y^3z
Evgesh-ka [11]
\bf \left.\qquad \qquad \right.\textit{negative exponents}\\\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}
\qquad \qquad
\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\qquad \qquad 
a^{{{  n}}}\implies \cfrac{1}{a^{-{{  n}}}}\\\\
-------------------------------\\\\

\bf \cfrac{-36x^4y^4z^5}{-12x^6y^3z}\quad 
\begin{cases}
36=2\cdot 2\cdot 3\cdot 3\\
12=2\cdot 2\cdot 3
\end{cases}\implies \cfrac{-36}{-12}\cdot \cfrac{x^4y^4z^5}{x^6y^3z^1}
\\\\\\
\cfrac{\underline{-2\cdot 2\cdot 3}\cdot 3}{\underline{-2\cdot 2\cdot 3}}\cdot \cfrac{x^4y^4z^5x^{-6}y^{-3}z^{-1}}{1}\implies \cfrac{3}{1}\cdot 
\cfrac{x^4x^{-6}y^4y^{-3}z^5z^{-1}}{1}

\bf \cfrac{3}{1}\cdot \cfrac{x^{4-6}y^{4-3}z^{5-1}}{1}\implies 
\cfrac{3}{1}\cdot\cfrac{x^{-2}y^{1}z^4}{1}\implies 
\cfrac{3x^{-2}yz^4}{1}\implies \cfrac{3yz^4}{x^2}

If triangle XYZ is congruent to triangle RST find RS
Alina [70]

Answer:

If two triangles Δ RST and Δ XYZ are similar, then corresponding angles are equal and their corresponding sides are proportional.

So here ∠R=∠X, ∠S=∠T and ∠T=∠Z
