Question

Fill in the blanks:
Total Surface area of a cone =____+____.
  1. Area of square + Area of Circle
  2. Area of sector + Area of Circle
  3. Area of Circle × Area of sector
  4. Area of triangle + Area of circle

A
Area of Circle × Area of sector
B
Area of triangle + Area of circle
C
Area of square + Area of Circle
D
Area of sector + Area of Circle
Solution
Verified by Toppr

A cone consists of a small circle and a sector of a larger circle. The arc of the sector has the same length as the circumference of the smaller circle.
So, Total surface area of cone = Area of sector + Area of the circle.
Hence, option B is correct.
