The area of a circle is 2464 cm2. What is the diameter of this circle? [Use π = $\frac{22}{7}$] |
56 cm 24 cm 48 cm 28 cm |
56 cm |
We know that, Area of a circle = πr2 Given, The area of a circle = 2464 cm2 = 2464 = πr2 = \(\frac{22}{7}\) × r2= 2464 r2= 784 r =\(\sqrt {784}\) = 28 So, diameter = 2r = 2 × 28 = 56 |
