the lateral area of a cone is 574 pi cm2. The radius is 19.6 cm. What is the slant height to the nearest tenth of a centimeter?
bulgar [2K]
\bf \textit{lateral area of a cone}\\\\
LA=\pi r\sqrt{r^2+h^2}~~
\begin{cases}
r=radius\\
\sqrt{r^2+h^2}=slant~height\\
-----------\\
LA=574\pi \\
r=19.6
\end{cases}
\\\\\\
574\pi =\pi (19.6)\sqrt{r^2+h^2}\implies \cfrac{574\pi }{19.6\pi }=\sqrt{r^2+h^2}
\\\\\\
\cfrac{574}{19.6}=\sqrt{r^2+h^2}

A piece of wire in the form of a rectangle with the dimensions 12 m by 10 m is bent to form a circle . Find the diameter of the
irakobra [83]

Answer:

14.01m

Step-by-step explanation:

Perimeter of the rectangular wire = circumference of the circle

Perimeter of the rectangular wire = 2(L+W)

Perimeter if the rectangular wire = 2(12+10)

Perimeter if the rectangular wire = 2(22)

Perimeter if the rectangular wire = 44m²

Circumference of the circle = πd

44 = πd

d = 44/3.14

d = 14.01m

Hence the circumference of the circle is 14.01m
