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
3/4 + 4 1/2 = 5 1/4
If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.
Part A
The expression "ma" is the same as "m*a" (m times a). To isolate 'a', we divide both sides by m. Division is the inverse operation of multiplication. Think of it as undoing multiplication
F = ma
F = m*a
F/m = m*a/m
F/m = a
a = F/m
Answer: a = F/m
Note: the slash "/" without quotes means "divide"
===========================================
Part B
Use the result from part A. We will plug F = -24 and m = 10 into that equation
a = F/m
a = -24/10
a = -2.4
Answer: -2.4
===========================================
Part C
We will use the equation F = m*a
F = m*a
24 = m*12 ... plug in F = 24 and a = 12
24/12 = m*12/12
2 = m
m = 2
Answer: 2
