Question

If the circumference of a circle is 154cm, find its area. (Use π = 22/7)​

Answer 1

circumference of a circle=2πr

ATQ

2πr=154cm

2×22/7×r=154cm

22×7×r=154/2

r=77×7/22

r=24.5

Area of circle=πr²

22/7×24.5×24.5

=1886.5

Answer 2

Answer:

area of Circle =. 1886.5 cm²

Step-by-step explanation:

given ,

circumference of Circle =154

to find , area

ATQ,

circumference = 2πr

154 =2×(22/7) ×r

r= (154×7) ÷ (22×2)

r= 24.5

area of Circle ⭕= πr²

therefore ,

area of Circle =. (22/7 )× 24.5 ×24.5

= 1886.5 cm²
