If the radius of the base and the slant height of a cone are 17cm and 25 cm, respectively, then what is the total surface area of the cone?
Show answer & explanation
Correct answer: C
Explanation
The Correct answer is option 3 i.e. 2244 cm2
Given that
If the radius of the base R = 17 cm
and the slant height of a cone L = 25 cm
Formula used
Total Surface Area of Cone = πR(R + L)
Calculation
⇒ T.S.A = (22/7) × 17 × (17 + 25)
⇒ T.S.A = 15708/7
⇒ T.S.A = 2244 cm2
