Question

if area of circle is 154 m², find its radius. also find circumference of circle​

Answer 1

Answer:

5 litre/2500ml=5×1000ml/2500ml=50/25=2

Answer 2

Here the area of the circle is given to be 154 m²

We will first find out the radius of the circle

area of circle = πr²

154 = (22/7) × r²

r² = 49

r² = √49

r = 7 m

Now, we will find out the circumference of the circle

circumference = 2πr

= 2 × (22/7) × 7

= 44 m

Hence, the radius and circumference of the circle will be 7 m and 44 m respectively
