Answer:
A=63.6 approximately
Step-by-step explanation:
P=14.28
p=1/4(2pi*r)
p=1/2pi*r
14.28=1/2pi*r
28.56=3.14*r
r=9...... approximately
A=1/4pi*r^2
A=0.25*3.14*81
A=63.6......approximately
Well, I don't what your question is, but I will assume that you want the dimensions of the rectangle after its dilation. So, multiply the dimensions of the rectangle by 2 to make it dilated.
Answer:
5' 10"
Step-by-step explanation:
We subtract by converting into one measurement. We will choose inches.
8'4"= 96"+4"=100" since 8' has 8(12) inches
2'6"=24+6=30" since 2' has 2(12) inches
Subtract.
100"-30"=70"
We convert back into feet and inches by dividing by 12.
70/12= 5' 10"
