A = ½ (10 + 12) (6)
A = 66
The area is 66 m².
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:

From here, we clear the value of x.
We have then:

Therefore, we have:
Answer:
7 times 1/7 equals 1
Volume is 4/3(3.14)(r)^2
the radius is 5.2 ft
Answer:
