Answer:
33.14 ft^2
Step-by-step explanation:
First find the area of the circle
The diameter is 20 ft so the radius is 1/2 of the diameter of 20*1/2 = 10 ft
A = pi r^2 = pi ( 10)^2 = 100 pi
The central angle is 38
That is a fraction of the circle, which is 360 degrees
38/360 = 19/180
Multiply the fraction of the circle by the area
19/180 * 100 pi
19/9 * 5 pi
Using 3.14 for pi
33.144444
To the nearest hundredth
33.14 ft^2
AD is one-fourth the length of CE.
If you look carefully, you would see that half of the diameter of CE is CD.
Then, line AD is the half of CD. So it is 1 / 4 the length of CE.

Answer:
28
Step-by-step explanation:
the ratio of their ages is 9 : 7 = 9x : 7x ( x is a multiplier ) , then
9x = 7x + 8 ( Jameelah is 8 years older than Anna )
Subtract 7x from both sides
2x = 8 ( divide both sides by 2 )
x = 4 , then
7x = 7 × 4 = 28
That is Anna is 28
<span>The ratio of boys to total children would be 4:6, which you could simplify since they are both divisible by 2, so you'd end up with 2:3. Of every 3 children, 2 are boys.</span>
