Answer:
10.6
Step-by-step explanation:
The missing part is the radius of the circle.
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here A = 353, this
πr² = 353 ( divide both sides by π )
r² = [tex]\frac{353}{\pi }[/tex] ( take the square root of both sides )
r = [tex]\sqrt{\frac{353}{\pi } }[/tex] ≈ 10.6 ( to the nearest tenth )
