Formula
--------------------------------------------------
Area of circle = πr²
--------------------------------------------------
Find radius
--------------------------------------------------
πr² = 75
r² = 75 ÷ π
r² = 23.87
r = √23.87
r = 4.89 cm (nearest hundreds)
--------------------------------------------------
Answer : radius = 4.89cm
