How to calculate the area of a sector</h3>
A sector is said to be a part of a circle made of the arc of the circle along with its two radii.
The formula for calculating the area of a sector is expressed as;
A = r²β/2
where
r is the radius of the circle
β is the angle subtended
Since the the hour hand travel during 5 hours, the subtended angle by the sector will be;
β = 360/5
β = 72 degrees
Given the following parameters
r = 16/2
r = 8in
Substitute into the formula
A = 8²(72π)/360
A = 40.192in
Therefore the hour hand travels 40.192in in 5 hours

Answer: B) 6</h3>
===========================================================
Explanation:
x = original side length
2x = double the side length
The old area is x^2. The new square area is (2x)^2 = 4x^2
new area = (old area) + 27
4x^2 = x^2 + 27
4x^2-x^2 = 27
3x^2 = 27
x^2 = 27/3
x^2 = 9
x = sqrt(9)
x = 3
The old original square has a side length of 3 units.
The new larger square has a side length of 2x = 2*3 = 6 units which is the final answer (choice B)
old area = 3^2 = 9
new area = 6^2 = 36
The jump from 9 to 36 is +27 to help confirm the answer.
