Answer:

a = equal sid \\  \\ </p><p>x = unequal side \\  \\ Area \:  of \:  isosceles  \: triangle \:  =  \sqrt{ {{a}^{2} }  -  \frac{ {x}^{2} }{4} } \\  =  \:  \sqrt{{ {6}^{2} }  -  \frac{ {8}^{2} }{4} } \\  =  \sqrt{36 - \frac{64}{4} }  \\  =   \sqrt{ \frac{144 - 64}{4} }  \\  =  \sqrt{ \frac{80}{4} }  \\  =  \sqrt{20}  \\  = 4.47 {m}^{2}

7) \\ 3 \sqrt{2}  + 7 \sqrt{2}  +  \sqrt{2}  - 5 \sqrt{3}  \\  = 4 \sqrt{2}  + 2 \sqrt{3}

9) \\  R = 2r \\ volume \: of \: sphere \:  = 4/3 πr³ \\  =  \frac{4}{3}  \times  \frac{22}{7}  \times 2r \times 2r \times 2r \\  = 33.52 \:  {r}^{3 } ( \: answer) \\  \\ { \huge{ \boxed{ \pink{ \boxed{ \purple{ \boxed{ \orange{ \boxed{ \ hope \: this \: helps \: u}}}}}}}}}
