Step-by-step explanation:
Using the formulas
A=πr2
C=2πr
Solving forC
C=2πA=2·π·154≈43.99115
thank you
Answer:
Given the area of the circle is 154 square metres.
Now
We know that
Area of circle = π × radius times radius.
154 sq. meter = π × radius times radius
154 sq. meter = 22/7 × radius times radius
154 ×7 ÷ 22 = radius times radius
On solving
We get
49 sq. meter = radius times radius
Now as we know that 49 is the square of 7.
Now, Radius is 7 meter.
Now
Circumference of circle = 2 times π times radius
Circumference of circle = 2 × 22 ÷ 7 × 7 meter
On solving
Circumference of circle = 44 metre
