1.) $70.69
2.) 1 gallon and of another
3.) $43.20
4.) $1,260
Step-by-step explanation:
1. Use the formula for the circumference of a circle (perimeter):
Since we have the diameter, substitute this into the formula and solve:
The circumference of the yard is 15π ft. Multiply this by the cost of fence per foot:
Round to the nearest hundredth (money lol $00.00):
$
2. Find the area of the ceiling:
Insert the values:
There is enough paint in a gallon to paint 196 ft². Subtract:
There would be enough paint left over to paint 76 ft².
You need 2 coats of paint, so you'd need enough to paint 120 ft² again. Subtract:
You would need enough extra paint to cover 44 ft². Divide this from a new gallon:
To have enough paint to make 2 coats, you would need 1 gallon and of another one.
3. Find the perimeter of the room:
The perimeter of the room is 54 ft².
Now find how much the boarder costs per foot:
One foot of boarder costs $0.80. Multiply this cost by the perimeter of the room:
The cost will be $43.20.
4. Find the area of the floor:
The flooring is 80 ft². Multiply this by the cost of the floor per foot:
The cost to buy the flooring is $960.
Write an equation for the cost to install the flooring:
f is the flooring. Insert the value:
The cost to install the flooring is $300. Add the costs together:
The total cost would come out to be $1,260.
