What is the difference between the total surface area and the curved surface area of a cone whose radius is 35 cm? (Take $π =\frac{22}{7}$) |
3850 cm2 3704 cm2 3750 cm2 3675 cm2 |
3850 cm2 |
We know that, Curved Surface Area of the cone (CSA) = πrl Base area = πr2 Total Surface Area (TSA) - Curved Surface Area of the cone (CSA) = πr2 We have given, Radius of cone = r = 35 cm We also know that, TSA - CSA = Base Area = πr2 = \(\frac{22}{7}\) x 35 x 35 = 3850 |
