Answer:

\boxed{Total \:  surface \: area \: of \:  hemisphere = 339.12\:  {cm}^{2} }

Step-by-step explanation:

Radius(r) = 6 cm

Total \:  surface \: area  \: of \:  hemisphere = 3\pi {r}^{2}  \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \times 3.14 \times  {6}^{2}  \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \times 3.14 \times 36 \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: \: \: \: \: \: \: \: \: \: \: \:   = 9.42 \times  \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: \: \: \: \: \: \: \: \: \: \: \:  =339.12 \:  {cm}^{2}

Answer:

1652w-1652  is equivalent to \left(2w-2\right)\left(826\right)

In other words:

\left(2w-2\right)\left(826\right)=\:1652w-1652

Step-by-step explanation:

Considering the expression

\left(2w-2\right)\left(826\right)

solving

\left(2w-2\right)\left(826\right)

=\left(826\right)\left(2w-2\right)

\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac

a=\left(826\right),\:b=2w,\:c=2

=\left(826\right)\cdot \:2w-\left(826\right)\cdot \:2

=826\cdot \:2w-826\cdot \:2

=1652w-1652

Therefore,

1652w-1652  is equivalent to \left(2w-2\right)\left(826\right)

In other words:

\left(2w-2\right)\left(826\right)=\:1652w-1652

Find the equation of the line specified. The slope is -4, and it passes through ( 5, 8).
ollegr [7]

Answer:

B. y= -4x + 28

Step-by-step explanation:

To find the equation of this line first put it into slope-point form, y-y_{1} =m(x-x_{1}) where y_{1} and x_{1} are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,

First, distribute the -4

y-8=-4x+20

Next, add 8 to both sides

y=-4x+28
