Answer:

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

hope it helped

If i have 2 apple and get 3 more then lose 2 how many do i have left
nydimaria [60]
You have 2 apples, get 3 more, and then lose 2 of them.

So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.
2 + 3 = 5

In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.
5 - 2 = 3

We now know that you are left with 3 apples.

\bf (x-2)^{2\div 3}=49\implies (x-2)^{\frac{2}{3}}=7^2\implies \stackrel{\textit{raising both sides by }\frac{3}{2}}{\left( (x-2)^{\frac{2}{3}} \right)^{\frac{3}{2}}=(7^2)^{\frac{3}{2}}} \\\\\\ (x-2)^{\frac{2}{3}\cdot \frac{3}{2}}=7^3\implies (x-2)^1=7^3\implies x=7^3+2\implies x=345
