A^2 + b^2 = c^2
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
sqrt 400 = c
20 = c <== the ladder is 20 ft long

How do you find the surface area for this one and what is the surface area for that?

klemol [59]

<span>First find the area of two sides (Length*Height)*2 sides, 60. Then find the area of adjacent sides (Width*Height)*2 sides, 43.2. And then find the area of ends (Length*Width)*2 ends, 72. Lastly add the three areas together to find the surface area, 175.2.</span>

Find the volume (in terms of pi) of a sphere of its surface area is 400 pi ft2

elixir [45]

$\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2\qquad \qquad \implies \stackrel{SA}{400\pi }=4\pi r^2\implies \cfrac{400\pi }{4\pi }=r^2 \\\\\\ 100=r^2\implies \sqrt{100}=r\implies \boxed{10=r} \\\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad V=\cfrac{4\pi \boxed{10^3}}{3}\implies V=\cfrac{4000\pi }{3}$

Answer:

$\large\boxed{d_2=15\ cm}$

Step-by-step explanation:

The formula of an area of a kite:

$A=\dfrac{d_1d_2}{2}$

d₁, d₂ - diagonals

We have A = 120 cm² and d₁ = 16 cm. Substitute:

$\dfrac{16d_2}{2}=120$

$8d_2=120$ <em>divide both sides by 8</em>

$d_2=15\ cm$
