ᴴᴱᵞᴬ

ᴴᴱᴿᴱ ᴵˢ ᵀᴴᴱ ᴬᴺˢᵂᴱᴿ

ᴳᴵᵛᴱᴺ :-

ᶜᴵᴿᶜᵁᴹᶠᴱᴿᴱᴺᶜᴱ = 22 ᶜᴹ

2πᴿ = 22

2 × 22/7 × ᴿ = 22

ᴿ = (22 × 7)/(22 × 2)

ᴿ = 7/2 ᶜᴹ

ᴺᴼᵂ,

ᴬᴿᴱᴬ ᴼᶠ ᶜᴵᴿᶜᴸᴱ = πᴿ²

=> 22/7 × 7/2 × 7/2

=> 38.5 ᶜᴹ²

Answer 2

Answer:

Step-by-step explanation:

Circumference = 22cm.

2πr = 22

2*22/7*r =22

r = 7/2 cm...

Area of circle = 2πr^2..

= 2*22/7*7/2*7/2 cm^2

= 38.5 cm^2...
