Answer:
9.60πcm²
Step-by-step explanation:
Area of circular disk, A = πr²
Differntiate A with respect to r
dA/dr = π * (2r^(2-1)) /(2-1) + C
dA/dr = π * 2r/1
dA/dr = 2πr
dA = 2πr * dr
dA = 2πrdr
dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm
dA = 2π * 24 * 0.2
dA = 9.60πcm²
The solution to your problem is as follows:
Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,
We get:
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26)
<span>. . .= 7,911×10^6 people
Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.

419.10>419.099 419.10 is greater than 419.009
Answer:
A and C
Step-by-step explanation:
There should be a 3:1 ratio from the miles to the hours. 3:1 is equivalent to 9:3 with a scale factor of 3. It is also equivalent to 3/4:1/4 with a scale factor of 1/4. Ergo, A and C are the answers. B and D wouldnt be the answers because they have a 1:3 ration instead
