Hey there! I'm happy to help!
The area of a circle is the radius squared multiplied by pi (we will use 3.14). We already have the area, so we will go backwards.
1441÷3.14≈458.9171975
We find the square root.
√458.9≈21.42235275
Now we have our approximate radius. The diameter is twice the radius.
21.42235275×2=42.8447055
I don't know exactly if they want you to round it or not, but the diameter is somewhere around there.
Have a wonderful day! :D
A^2+b^2= 15^2
b=a-3
Use substitution
a^2+(a-3)^2= 225
a^2+a^2-6a+9=225
2a^2-6a=-216
2a^2-6a+216=0
2(a^2-3a+108)
2(a-12)(a+9)
(a-12)=0
a=12
(a+9)=0
a=-9
A is -9 or 12, but since an object can't have a negative length or width, a must be 12.
Plug this value of a in.
b=(12)-3
b=9
Final answer: Length=9, width=12
