A whole hour or revolution is 60 minutes and 360° so the area of a sector is:
A/πr^2=α/360
A=απr^2/360...now we need to find the angle α/360=5/60, α=30° so:
A=30πr^2/360
A=πr^2/12 and r=11.25ft so
A=11.25^2*π/12
A≈33.13 ft^2
We first calculate the area of the entire pool and the side walk.
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
Answer:
The diameter of the wheel is 32 centimeters
Step-by-step explanation:
we know that
The <u><em>intersecting chords theorem</em></u> states that the products of the lengths of the line segments on each chord are equal.
so
In this problem

substitute the given values

solve for x

Remember that
LK goes through the center of the wheel
That means----> LK is a diameter

therefore
The diameter of the wheel is 32 centimeters
Answer:
equation is y = x+4
Step-by-step explanation:
m = 1
y = mx + b
3 = 1*(-1)+b
3 = -1+b
b = 4
so
again
y = mx+b
y = 1x +4
so y = x+4
