pi·(7.2/2)^2·x = 2·pi·(7.2/2)^2 + 2·pi·(7.2/2)·x
x = 4.5 = 4 1/2
O = V = 1458/25·pi = 58.32·pi
9.1/3575
use long division like this
_<u>0.</u>_________
3575|91.000000
we find how many of 3575 fit into the 91
it's too big so we go farther
how many 3575 go into 910
too big so we go farther
how many 3575 go into 9100
the answer is 2 so put that in the correct place and mulitply that and put that in the correct place. then we subtract
_<u>0.</u><u>02</u>_________
3575|91.000000
-<u>71.50</u>
19.50
bring down the next number
find how many go into 19.500
the answe ris 5
_<u>0.</u><u>02</u><u>5</u>_________
3575|91.000000
-<u>71.50</u>
19.500
-<u>17.875</u>
1.625
bring down he next zero ( I fast forward and skip steps for convinience)

and so on untill infinity so the answe ris 0.0254555555555555 (enless fives)
Answer:
<h2>0i</h2>
Step-by-step explanation:
The imaginary number has form:
<em>a + bi</em>
<em>a</em><em> - real part</em>
<em>bi</em><em> - imaginary part</em>
<em>i</em><em> - imaginary unit (i = √-1)</em>
We have the number 9.
<em>9</em><em> is a real part</em>
An imaginary part is equal 0.
Therefore the imaginary part of number 9 is 0i.
Answer:
NOT nets = A, C, D, F
Nets = B, E, G, H
Figure B (Triangular prism)
SA: 3 rectangles + 2 triangles
Rectangles: (20·8) + (20·10) + (20·6) = 480 ft²
Triangles: (8·6)/2 + (8·6)/2 = 48 ft²
Total SA: 528 ft²
Figure E (Square pyramid)
SA: 1 square + 4 triangles
Square: 10·10 = 100 yd²
Triangles: (12·10)/2 + (12·10)/2 + (12·10)/2 + (12·10)/2 = 240 yd²
Total SA: 340 yd²
Figure G (Rectangular prism)
SA = 2 wide rectangles + 4 narrow rectangles
Wide: (7·11) + (7·11) = 154 cm²
Narrow: (2·7) + (2·7) + (11·3) + (11·3) = 94 cm²
Total SA: 248 cm²
Figure H (Cube)
SA = 6 squares
Squares: 6 x (1·1) = 6 m²
Total SA: 6 m²
I hope this helps and God bless!
