-10 is not a solution to the equation
Step-by-step explanation:
I don't really have an explanation
Answer:
It should be 10 raised to power 2 which is a hundred.
(2.34/ 7.89) times 100 = ˜29.65%
Answer:
The circumference of the circle is 52π
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 676π
r = radius
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(676π/π)
r = √(676)
r = 26
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = π * 2 * 26
c = 52π
The circumference of the circle is 52π
