Answer:
Solution given:
radius [r]=2cm
height [h]=8cm
total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
- 2πr(r+h)
- 2π*2(2+8)
- 40π or 125.66cm²
<u>total surface area of cylinder</u><u>40π or 125.66cm²</u><u>.</u>
The value of interior angle x for the given pentagon if found as 88 degrees.
<h3>What is termed as the pentagon?</h3>
- A pentagon is a two-dimensional polygon with 5 sides and 5 angles.
- This shape should have five sides and form a closed two-dimensional figure.
- A closed figure consists of each of its sides intersecting to form vertices.
- Five diagonals connect the five vertices to one‘s opposite vertices in a pentagon shape.
- Each interior angle in a regular pentagon is 108°, so each exterior angle is 72°.
For the given question;
The exterior angles of the pentagon are given in figure.
Find all the interior angles for given angles using linear pair as all are straight lines.
- 180 - 62 = 118
- 180 - 33 = 147
- 180 - 114 = 66
- 180 - 59 = 121
The sum of all the interior angle of pentagon is 540.
Thus,
118 + 147 + 66 + 121 + x = 540
x = 540 - 452
x = 88
Thus, the value of interior angle x for the given pentagon if found as 88 degrees.

The solution for this problem is:
dV/dt = r/(t + 1)², V(0) = $500000, V(1) = $500000 - $200000 = $300000
∫dV = r∫ 1/(t + 1)² dt
V(t) = -r/(t + 1) + C
500000 = -r/(0 + 1) + C
400000 = -r/(1 + 1) + C
C = 300000, r = -100000
V(t) = 100000/(t + 1) + 300000
V(6) = 100000/(6+ 1) + 300000
V(6) = 14285.7143 + 300000
V(6) = $314285.71
