Answer 1

Answer: Radius = 10.48 cm

Step-by-Step Solution:

Radius (r) = ?
Area (A) = πr² = 345 sq. cm

Therefore,
πr² = 345
3.14 * r² = 345
r² = 345/3.14
r² = 109.87
r = √109.87
=> r = 10.48

Radius (r) = 10.48 cm

Answer 2

5.9

Explanation:

It's because area is 345

1. Formula , A=πr2
2. Find the √ of 345
3. 18.6=3.14×f2f
4. R = 5.9
