Answer:

We use the formula:

S 10 = 8 · [(1/2)^9 - 1] / (1/2 - 1 );

Then, S 10 = 8 · ( 1/512 - 1 ) / ( 1/2 - 1 );

S 10 = 8 · ( - 511 / 512 ) / (-1 / 2 );

S 10 = ( - 511 / 64 ) · ( - 2 );

S 10 = + 511 / 32;

S 10 = 15.96;

marin [14]
Figure=1rectangle+2 semicircles
1semicircle=1/2circle
2 (1/2 circles)=1 circle
figure=1 rectangle+1 circle
area of rectangle=legnth times width
area of circle=pir^2

so the width of the rectangle=diameter of the circle
widht=4

diameter=2r
d/2=r
width=d=4
4/2=r=2

area of circle=3.14 times 2^2
are of circle=3.14 times 4
aera of circle=12.56

area of rectangle=11 times 4
area=44

total=add them up
12.56+44=56.56 cm^2
