Answer: there are many ways to calculate area. you can simply use the base*height if you are doing a square or rectangle, sort of thing. If you are doing a circle it would be pi*radius^2

Step-by-step explanation:

Gelneren [198K]

The total surface area of a cylinder is given by the formula

\begin{gathered} A_{cylinder}=2circular\text{ area+curved surface area} \\ =2\pi r^2+2\pi rh \end{gathered}

Given diameter, d=12meters, we will solve for radius

\begin{gathered} \text{diameter,d}=2\times radius,r \\ d=2r \\ r=\frac{d}{2} \\ r=\frac{12m}{2} \\ r=6m \end{gathered}

The height is given as 9meters

Substituting for r and h in the formula will give

\begin{gathered} A_{cylinder}=2\pi r^2+2\pi rh \\ r=6m;h=9m;\pi=3.14 \\ A_{cylinder}=2\times3.14\times6^2+2\times3.14\times6\times9_{} \end{gathered}\begin{gathered} A_{cylinder}=6.28\times36+6.28\times54 \\ =226.08+339.12 \\ =565.2m^2 \end{gathered}

Hence the surface area of the cylinder is 565.2m²

Find the value of root 121 + 3 over root 125
NemiM [27]

Answer:

\mathrm{Decimal:\quad }\:1.25219\\\frac{14\sqrt{5}}{25}

Step-by-step explanation:

\frac{\sqrt{121}+3}{\sqrt{125}}\\\sqrt{125}=5\sqrt{5}\\=\frac{\sqrt{121}+3}{5\sqrt{5}}\\\sqrt{121}=11\\=\frac{11+3}{5\sqrt{5}}\\\mathrm{Add\:the\:numbers:}\:11+3=14\\=\frac{14}{5\sqrt{5}}\\\mathrm{Rationalize\:}\frac{14}{5\sqrt{5}}:\quad \frac{14\sqrt{5}}{25}\\=\frac{14\sqrt{5}}{25}
