Let's calculate each area.
4 m:
We need to divide it by 2 to find the radius.
4÷2=2
Now let's put it in the formula.
2²π
4π=12.5663706≈13
6 m:
We need to divide it by 2 for the radius.
6÷2=3
Now put it in the formula.
3²π
9π=28.2743≈28
Now subtract 13 from 28.
28-13=15
So, the difference between their area is 15 m².
Answer:
first bring x value together
Step-by-step explanation:
like 2x and 3x together and then take 5/3 to RHS and solve
Answer:
it would simplify to 12/1 or just 12
Answer:
102= 72x; x = around 1.42
Step-by-step explanation:
p must be positive. If p is negative, the equation has no real solutions. This is because any number to the power of 2 is always positive. Therefore, if p is positive, there are 2 real number solutions: sqrt(p) and -sqrt(p).
Hope this helps,
