Download Solution PDFWhat is the difference between the total surface area and the curved surface area of a cone whose radius is 35 cm? (Take π = \(22\over 7\))
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGiven:
Radius of cone = r = 35 cm
Concept used:
Curved Surface Area of the cone (CSA) = \(\frac{22}{7}\) x r x l
Total Surface Area (TSA) - Curved Surface Area of the cone (CSA) = πr2
r = radius of the base
l = slant height of the cone
Base area = πr2
Calculation:
TSA - CSA = Base Area
TSA - CSA = \(\frac{22}{7}\) x r x r
TSA - CSA = \(\frac{22}{7}\) x 35 x 35
TSA - CSA = 3850
Hence, the correct answer is option 1).
