Left triangle area
.. (1/2)*(30 ft)*(72 ft) = 1080 ft^2
Middle walkway area
.. (20 ft)*(72 ft) = 1440 ft^2
Right triangle area
.. same as left triangle area, 1080 ft^2
Total area
.. 1080 ft^2 +1440 ft^2 +1080 ft^2 = 3600 ft^2
_____
Check:
Parallelogram area = base*height = (50 ft)*(72 ft) = 3600 ft^2
The answer is B hope this helps
We know that circumference = diameter * 3.14, so in order to find the diameter all we have to do is:
circumference/3.14 = diameter
So, we can plug in the value of the circumference:
34 / 3.14 = 10.82
The exact answer is 10.82.
The approximate answer is 11.
Answer:
area is how big the surface is，volume is the capacity of the shape
7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
