Full solution

Q. Find the circumference of the circle below:
  1. Identify Radius: Step 11: Identify the radius of the circle from its equation.\newlineThe equation of the circle is x2+y2=36x^2 + y^2 = 36. This is in the standard form (x−h)2+(y−k)2=r2(x - h)^2 + (y - k)^2 = r^2, where rr is the radius. Here, r2=36r^2 = 36.\newlineCalculation: r=36=6r = \sqrt{36} = 6.
  2. Calculate Circumference: Step 22: Calculate the circumference using the formula C=2πrC = 2\pi r. We know the radius (rr) is 66. The formula for the circumference (CC) of a circle is C=2πrC = 2\pi r. Calculation: C=2×π×6=12πC = 2 \times \pi \times 6 = 12\pi.
