Put a line over the repeating number.
We have that
1 1/2 acres-------------> 1.5 acres
one hour----------------> 60 minutes
Step 1
I proceed to make a rule of three
<span>if Jami can now mow 1/6 acre -----------------------> in 8 minutes
1.5 acres----------------------------------------------> X
X=1.5*8/(1/6)=72 minutes
72 minutes > 60 minutes
therefore
</span><span>Jami can not mow 1 1/2 acres in an hour
</span><span>The time required by jami to mow 1 1/2 acres is 72 minutes</span><span>

Answer:
The area is 12.56, and the circumference is 12.56.
Step-by-step explanation:
For the area,
We need to use the formula A=3.14*radius*radius
So we plug it in, and we get 3.14*2*2, which is 12.56 centimeters squared.
For circumference, we need to do,
C = 3.14*diameter
To find the diameter we need to do 2 (radius) x 2 which is 4
Plugging it in that would be 3.14 * 4 which is 12.56
So, in this case, the area is 12.56, and the circumference is also 12.56.
