A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)
8,000,000 + 200,000 + 5,000
Answer:
-7
Step-by-step explanation:
6x - 5 = -47 subtract 5 from both sides so the x is alone
6x = -42 divide by 6 so you can find what x equals
x= -7
Uh 10... because 10 is 10
A=(pie) squared times 1/2
I think this is correct but I’m not sure
