Question

Area of the circle is 38.5 cm2.Its circumference is​

Answer 1

Answer:

22CM

Step-by-step explanation:

AREA OF A CIRCLE = PIE × r^2

38.5=22/7×r^2

38.5×7/22=r^2

12.25=r^2

√12.25=r

r=3.5CM

CIRCUMFERENCE OF CIRCLE=2×pie×r

=>2×22/7×3.5 (7 divides 3.5)

=>44×0.5

=>22CM

THEREFORE, CIRCUMFERENCE OF THE CIRCLE IS 22CM.
