Question

if circumference of a circle is 220 m what is its area​

Answer 1

Step-by-step explanation:

here's your answer:

Given:

Circumference = 220 m

To find:

Diameter and area

Solution:

First it is necessary to find radius

Circumference = 2πr

220 = 2× 22/7 × r

220 × 7 / 2 × 22 = r

5 × 7 = r ( After cancellation)

35 = r

Therefore r is 35 m

Diameter = 2r

= 2 × r

=2 × 35

= 70

Therefore Diameter is 70 m

Area = πr^2

= 22/7 × 35 × 35

= 22 × 5 × 35

= 3850 m^2

Hope this helps ☺️

Answer 2

Answer:

3850m^2

Step-by-step explanation:

Circumference of the circle = 220 m

We know that,Circumference of a circle = 2πr

according to the question,

2πr =220

2×22/7×r=220

r= 220×7÷22×2

r= 1540÷44

r = 35

Area of the circle = πr^2

= 22/7 ×35^2

= 22/7×35×35

=22×5×35

=3850m^2
