<h3><u>Answer</u> :</h3>

$\bigstar\:\boxed{\bf{\purple{x^{\frac{m}{n}}}=\orange{(\sqrt[n]{x})^m}}}$

Let's solve !

$:\implies\sf\:25^{\frac{3}{2}}$

$:\implies\sf\:(\sqrt[2]{25})^3$

$:\implies\sf\:5^3$

$:\implies\boxed{\bf{\red{125}}}$

<u>Hence, Oprion-D is correct</u> !

LAST OF MY GEOMETRY PLZ HELP

makvit [3.9K]

Answer:

Step-by-step explanation:

14) 2x - 10 = 80 {alternate interior angles are equal}

2x = 80 + 10

2x = 90

x = 90/2

x = 45°

15) 3x + 120 = 180 { co interior angles are supplementary}

3x = 180 - 120

3x = 60

x = 60/3

x = 20°

16) 3x + 15 = 135 {corresponding angles are equal}

3x = 165 - 15

3x = 150

x = 150/3

x = 50°

Find the total surface area of this cone. Round to the nearest tenth.

leva [86]

Step-by-step explanation:

for given cone:

h = 3 ft, r = 3 ft

Let l be the Slant height of cone.

$\therefore \: l = \sqrt{ {h}^{2} + {r}^{2} } \\ = \sqrt{ {3}^{2} + {3}^{2} } \\ = \sqrt{9 + 9} \\ = \sqrt{2 \times 9} \\ \therefore \: l= 3 \sqrt{2} \: ft \\ \\ total \: surface \: area \: of \: cone \\ = \pi \: r(l + r) \\ = 3.14 \times 3(3 \sqrt{2} + 3) \\ = 9.42 \times 3( \sqrt{2} + 1) \\ = 28.26 \times (1.414 + 1) \\ = 28.26 \times 2.414 \\ = 68.21964 \\ \approx \: 68.2 \: {ft}^{2}$
