Answer:
option A)14 units.
Step-by-step explanation:
Area of a circle is = πr²
To find the radius of the circle we should substitute the value of area in this formula and π=22/7 (constant)
given, A(area)=616 sq.units and π=22/7
Area of a circle is = πr²
=> 616 = 22/7 x r²
=> 616 x 7 = 22 x r²
=> r² = 616 x 7/22
=> r² = 4312/22
=> r² = 196
=> r = √196
=> r= 14 units. (since 14 x 14=196).
Therefore, your answer will be option A) 14 units
