As per the given data,
Perimeter of the upper end of a frustum of a right circular cone $=44cm$
So, $2\pi {{r}_{1}}=44$
$2\left( 22/7 \right){{r}_{1}}=44$
(radius of upper end of a frustum of a right circular cone ) ${{r}_{1}}=7cm$
Perimeter of the lower end of a frustum of a right circular cone $=33cm$
So, $2\pi {{r}_{2}}=33$
$2\left( 22/7 \right){{r}_{2}}=33$
${{r}_{2}}=21/4cm$
Now,
Let us assume the slant height of the frustum of a right circular cone be L.
$L=\sqrt{{{\left( {{r}_{2}}-{{r}_{1}} \right)}^{2}}}+{{h}^{2}}$
$=\sqrt{{{\left( 7-5.25 \right)}^{2}}}+{{16}^{2}}$
Therefore, L $=16.1cm$
As we known that,
the curved surface area of the frustum cone is given by formula $\pi \left( {{r}_{1}}+{{r}_{2}} \right)l$
$=\pi \left( 7+5.25 \right)16.1$
Therefore, curved surface area of the frustum cone is $619.65c{{m}^{2}}$
Next, according to the question,
The volume of the frustum cone is given by the formula $1/3\pi \left( r_{2}^{2}+r_{1}^{2}+{{r}_{1}}{{r}_{2}} \right)h$
By substituting the given values,
$=1/3\pi \left( {{7}^{2}}+{{5.25}^{2}}+\left( 7 \right)\left( 5.25 \right) \right)\times 16$
$=1898.56c{{m}^{3}}$
Thus, volume of the cone is $1898.56c{{m}^{3}}$
As we known that the total surface area of the frustum cone
$=\pi \left( {{r}_{1}}+{{r}_{2}} \right)\times L+\pi r_{1}^{2}+\pi r_{2}^{2}$
So by putting given values,
$=\pi \left( 7+5.25 \right)\times 16.1+\pi {{7}^{2}}+\pi {{5.25}^{2}}$
$=\pi \left( 7+5.25 \right)\times 16.1+\pi \left( {{7}^{2}}+{{5.25}^{2}} \right)=860.27c{{m}^{2}}$
Therefore, the total surface area of the frustum cone is equal $860.27c{{m}^{2}}$
