Answer 1

Step-by-step explanation:

Solution :-

Given - Circumference of circle = 22 cm

Let the radius of the given circle be 'r'

Circumference of a circle = 2πr

⇒ 22 = 2 × 22/7 × r

⇒ r = (22 × 7)/(22 × 2)

⇒ r = 154/44

⇒ r = 3.5 cm

Area of circle = πr²

⇒ 22/7 × 3.5 × 3.5

⇒ 269.5/7

= 38.5 cm²

So, the area of the given circle is 38.5 cm²

Answer 2

Answer:

3.5 is Radius , 38.5 is Area

Step-by-step explanation:

Circumference of Circle = 2 × Pie × R

22 cm = 2 × 22/7 × R

22 × 7/22×2 = R

3.5 = Radius

Area of Circle = Pie × (r)^2

Area of Circle = 22/7 × (3.5)^2

Area of Circle = 22 × 12.25 / 7

Area of Circle = 269.5/7

Area of Circle = 38.5 cm^2

Hope it helps!!
