Answer:
It will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck
Step-by-step explanation:
Diameter of swimming pool = 27 feet
Radius of pool r=
Surrounding the pool is a deck that extends 5 feet from the edges of the pool
Outer radius R = 13.5+5=18.5
Area of deck = Outer area - Inner area
Area of deck =
Area of deck = 
Area of deck = 
Cost of painting 1 sq.feet = $0.85
Cost of painting 502.4 sq.feet = 
Perimeter of deck = 
Cost of fencing 1 foot = $8.25
Cost of fencing 116.18 foot = 
Hence it will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck
When expanding number, we should separate the numbers according to the places like the number 275 written in expanded form 200+70+5. So, in this question we must likely done like this. The number is 39,005 the sum that is written on expanded form is 30,000+9,000+5.
1.Design a number line containing five (5) points
For this case what you should do is place a line with five points.
You can think of one of the axes of the Cartesian plane, for example, the x-axis. We place five separate points in that line the same distance.
line: 0 1 2 3 4 5
a. Round off the total population to the nearest hundred thousand people
nearest hundred thousand means
100,000
Then rounding off we have:
10,160,555
hundred thousand: 10,161,000
b. Round off Benin's area in square miles to the nearest thousand.
nearest thousand means
1,000
Then rounding off we have:
43,475
thousand: 44,000
Round off the number of miles of surfaced roads to the nearest ten. nearest ten means
10
Then rounding off we have:
870
ten: 870
d. Round off the number of people who live in rural areas to the nearest million
nearest million means
1,000,000
Then rounding off we have:
3,657,790
million: 4,000,000
