Answer:
Step-by-step explanation:
Firstly, we've to draw a triangle according to the givens. (See the attached file)
<u>Then according to the Trigonometric Ratios:</u>
Cos (I) = Adjacent / Hypotenuse
Cos (I) = 62 / 88
Cos (I) = 0.704
< I = Cos ⁻¹ (0.704)
< I = 45.2°

If we let a = 9,
y(t) = A x 3^(t/9)
(i) If y(t) = 1000 a t = 0, then
1000 = A (3)^(0/a)
A = 1000
(ii) At t= 5
y(5) = 1000 (3)^(5/9)
y(5) = 1841
(iii) At y(t) = 100,000
100,000 = 1000 (3)^(t/9)
t = 37.7 years
(iv) Taking the derivative and substituting, t = 0 , and t = 10
for t = 0
dy/dt = 122 people/year
for t = 10
dy/dt = 414 people/year

Answer:
Half of 3 is 1.5(new radius)
1.5^2 = 2.25
2.25 x 3.14 = 7.065
7.065 x 2 = 14.13(area of two circles)
2 x 3.14 x 1.5 = 9.42
9.42(circumference) x 4(height) = 37.68(area of lateral)
Add the given areas:
37.68 + 14.13 = 51.81 cm2 is your answer.
