Question

What is the area of the circle whose circumference is 44 cm?​

Answer 1

Circumference = 2πr

44 = 2πr

r = 44/2π

r = 22/(22/7)

r = 22/22 × 7

r = 7 cm

Answer 2

Answer:

$154$

Step-by-step explanation:

circumference = 2πr

44 = 2πr , ( Given Circumference = 44 )

22 = πr

$22 = \frac{22}{7} \times r \\ \\ \frac{22 \times 7}{22} = r \\ \\ r = 7$

Now,

Area of Circle = πr²

π(7)²

$49 \times \frac{22}{7} \\ \\ 7 \times 22 \\ \\ 154$

As we know that ,

$\pi = \frac{22}{7}$
