Answer:

Step-by-step explanation:

$|\angle AEC|=(4x)^o \quad\implies\quad |\angle AED|=180^o-(4x)^o\\\\\\\widehat{AC}=120^o\quad\implies\quad |\angle AOC|=120^o\\\\|\angle AOC|=120^o \quad\implies\quad |\angle ADC|=\frac12\cdot120^o=60^o\\\\\\\widehat{BD}=(2x)^o\quad\implies\quad |\angle BOD|=(2x)^o\\\\|\angle BOD|=(2x)^o \quad\implies\quad |\angle ADC|=\frac12\cdot(2x)^o=x^o\\\\\\ \Delta ADE:\\\\180^o-(4x)^o+60^o+x^o=180^o\\\\-(3x)^o=-60^o\\\\x=20^o\\\\\\|\angle AED|=180^o-4\cdot20^o=100^o$

Find the area of sphere of radius 4 cm

marin [14]

<h3>✠ Given:-</h3>

Radius of the Sphere = 4 cm

Area of the Sphere = ??

<h3>✠ Solution:-</h3>

⚘ Here , we Have Given That Radius of the Sphere is 4 cm and we have to find the Area of the Sphere , We know that formula used to find the area; <u>Area of Sphere = 4πr²</u>.....

☼ <u>Calculating the Area of the Sphere</u>;

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \: \: 4 \: \pi \: r {}^{2} \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \: \: 4 \: \times \: \frac{22}{7} \: \times \: 4 {} \: ^{2} \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \: \: 4 \: \times \: \frac{22}{7} \: \times \: 4 \: \times \:4 \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \: \: 4 \: \times \: \frac{22}{7} \: \times \: 16 \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \:\: \frac{4 \: \times \: 22 \: \times \: 16 \: }{7} \: \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \:\: \frac{ \: \: 1408\: \: \: }{7} \: \\$

$\\ \sf \implies \: Area_{ \red{ \{Sphere \}}} \: = \:\: \cancel{\frac{ \: \: 1408\: \: \: }{7} } \: \\$

$\\ \implies{ \underline{ \boxed{\sf{ \: Area_{ \red{ \{Sphere \}}} \: = 201.14 \: \: cm }}}}\\ \\$

Henceforth, The Area of Sphere is 201.14 cm...!!

$\\ \\ ✠ \: \: { \underline{\bf { \color{blue}{ \: \: Additional \: \: Information :- \: \: }}}} \\ \\$

⇥ Perimeter of rectangle = 2(length× breadth)

⇥ Diagonal of rectangle = √(length ²+breadth ²)

⇥ Area of square = side²

⇥ Perimeter of square = 4× side

⇥ Volume of cylinder = πr²h

⇥ T.S.A of cylinder = 2πrh + 2πr²

⇥ Volume of cone = ⅓ πr²h

⇥ C.S.A of cone = πrl

⇥ T.S.A of cone = πrl + πr²

⇥ Volume of cuboid = l × b × h

⇥ C.S.A of cuboid = 2(l + b)h

⇥ T.S.A of cuboid = 2(lb + bh + lh)

⇥ C.S.A of cube = 4a²

⇥ T.S.A of cube = 6a²

⇥ Volume of cube = a³

⇥ Volume of sphere = 4/3πr³

⇥ Surface area of sphere = 4πr²

⇥ Volume of hemisphere = ⅔ πr³

⇥ C.S.A of hemisphere = 2πr²

⇥ T.S.A of hemisphere = 3πr²

What is the slope of the line whose equation is y−4= StartFraction 5 Over 2 EndFraction.(x−2)?

Yuki888 [10]

For this case we must find the slope of the following equation:

$y-4 = \frac {5} {2} (x-2)$

By definition, the point-slope equation of a line is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

$(x_ {0}, y_ {0})$ : It is a point through which the line passes

m: It's the slope

So, the slope of the given equation is:

$m = \frac {5} {2}$

Option D
