Answer 1

Answer 2

$\huge{\red{\mathtt{\underline{Answer:}}}}$

$\mathtt{r_{1} = \frac{132 \times 7 }{2 \times 22} = 21\:cm}$

$\mathtt{r_{2} = \frac{88 \times 7 }{2 \times 22} = 14\:cm}$

$\mathtt{Slant\:height\:of\:frustum, }$

• $\bold{\boxed{\red{\mathtt{l = \sqrt{{h}^{2} + {(r_{1}-r_{2})}^{2}}}}}}$

—» $\mathtt{r_{1} - r_{2} = 21 - 14 = 7}$

—» $\mathtt{\sqrt{{24}^{2}+{{7}^{2}}}}$

—» $\mathtt{\sqrt{576 + 49}}$

—» $\mathtt{\sqrt{625}}$

—» $\mathtt{\sqrt{25}}$
