The picture in the attached figure

we know that
surface area of the figure=[surface area of hemisphere]+[surface area of the cylinder]

step1
find the surface area of hemisphere
surface area hemisphere=2*pi*r²
for r=8 in
surface area hemisphere=2*pi*8²-----> 401.92 in²

step 2
find the surface area of the cylinder
surface area of cylinder=area of the base+perimeter of the base*height

area of the base=pi*r²
for r=8 in
area of the base=pi*8²----> 200.96 in²

perimeter of the base=2*pi*r----> 2*pi*8-----> 50.24 in

surface area of cylinder=200.96+50.24*7-----> 552.64 in²

step 3
surface area of the figure=[surface area of hemisphere]+[surface area of the cylinder]
surface area of the figure=[401.92]+[552.64]-----> 954.56 in²

the answer is
954.56 in²

The sum of 5 times a number and <br> minus −​2, plus 7 times a​ number
Olenka [21]

Answer:

12x + 2

Step-by-step explanation:

Let the number be represented by x.

Then five times the number = 5*x

Seven times the number = 7*x

Sum of 5 times the number minus -2 = \[5*x - (-2)\] = \[5x +2\]

Adding seven times the number to this expression yields, \[5x+2+7x\]

\[= (5+7)x+2\]

\[= 12x+2\]

So the simplified expression corresponds to 12x + 2.
