Question

area of circle 44m² .find its circumference​

Answer 1

Step-by-step explanation:

WKT

area of a circle = πr²

circumference = 2πr

also, it's given that area is 44cm²

So,

44 = 3.14 × r²

r² = 14cm {it's 14.01 but as I took 3.14 than 22/7 it'll be 14}

r = 3.74

Now,

circumference = 2 × 3.14 × 3.74

c = 23.50

Answer 2

༆ Answer༆

● Area of circle = π r²

↦44 m² = π r²

↦44/π = r²

↦r² = 44 × 7/22

↦r² = 14

↦r = √14

● Perimeter of circle = 2 π r

↦$\sf Perimeter ~of ~circle = \frac{2 \times 22 \times \sqrt{14} }{7}$

↦$\sf Perimeter~ of~ circle = \frac{2 \times 22 \times \sqrt{7} \times \sqrt{2} }{ \sqrt{7} \times \sqrt{7} }$

↦$\sf Perimeter~ of ~circle = \frac{2 \times 22 \times \sqrt{2} }{ \sqrt{7} }$

↦Perimeter of circle = 2×22×0.54

↦Perimeter of circle = 23.76 m

Your answer = 23.8 m (approx.)
