Answer: 18.86 feet
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = πD
Where D represents the diameter of the circle.
The circumference of the inner circle is 44 ft. It means that
22/7 × D = 44
22D = 7 × 44 = 308
D = 308/22
D = 14 ft
The distance between the inner circle and the outer circle is 3 ft. This means that the diameter of the outer circle would be
14 + 3 + 3 = 20 ft
Circumference of the outer circle is
22/7 × 20 = 62.86 ft
The number of feet by which the circumference of outer circle is greater than the circumference of the inner circle is
62.86 - 44 = 18.86 feet
You would do tan<span>Ɵ = 9/12
tan^-1(9/12) = </span><span>Ɵ
</span><span>Ɵ = 36.87 degress
make sure your calculator is in degree mode

Answer:
A and B
Step-by-step explanation:
Answer:
A = 2.63
B = 2
Step-by-step explanation:
To find the population density, what we need to do simply is divide the population by the area of the UK
mathematically, that would be;
(6.41 * 10^7)/243,610 = 263.125
To the nearest whole person= 263 people/ square meter
So now we want to write 263 in standard form = 2.63 * 10^2
So this means A = 2.63 and B = 2
