First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65＝85.722 and 2*3.14*11.25＝70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.
Area=legnth times width
if legnth=x
and
area=400
400=x times width
wait
SQUARE painting
legnth=width
width=x
400=x times x
400=x^2
sqrt both sides
20=x
answer is 20 in
equation is
400=x times x
Answer:
Step-by-step explanation:
Even if I don't know the options I can give all the option that will be right for expending this. Just look at each step and see which one is one of the options.
The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12
