Ln(5^x) = ln(81.2)
xln(5) = ln(81.2)
x= ln(81.2)/ln(5)
x= ln(406/5)/ln(5)
x = ln(406) - ln(5)/ln(5)
log (ab) = log(A) + log (B)
ln(2) +ln7 + ln(29 - ln(5)/ln(5)
x = 2.7320 (4dp)
General equation is
an = a1 + (n-1)d where a1 = first term and d = common difference
here d= 2-5 = -3 and a1 = 5
so an = 5 -3(n-1) is the explicit equation required.
Lateral Cone Area = PI * radius * slant height
slant height ^ 2 = 6^2 + 10^2
slant height ^ 2 = 36 + 100
slant height ^ 2 = 136
slant height ^ 2 = 11.6619037897
Lateral Cone Area = PI * 6 * 11.66
Lateral Cone Area = 219.6744
That's my calculation and I used an online calculator which says the same thing. It is NOT one of the choices.

Answer:</h3>
We know that,
<u>Area of rectangular bulletin = L × B</u>
- L × 50 = 45
- L = 45/50 = 9/10cm
<u>Hence, Length of rectangular bulletin is 0.9cm</u>.
