Answer 1

c option is the best answer

Answer 2

Answer: OPTION (D).

Step-by-step explanation:

Area of circle = πr²

According to the question,

πr² = 49π²

r² = 49π/π

r² = 49

r = √49

r = 7 units.

Now we have to find the perimeter or circumference so,

Circumference of a circle = 2πr

2×π×7

14π units.

Hence, option is (D) is correct.

You can also simplify it by putting the value of π,

14×22/7

2×22

44 units.

44 units can also be correct but according to your question, 14π is correct.
