Detailed Solution
Download Solution PDFGiven:
Curved surface area of a cone = 4664 \(cm^2\)
radius = 28 cm
Formula used:
Curved surface area of cone = π × r × l
where l = slant height; r = radius
Calculation:
Curved surface area = 4664
⇒ π × r × l = 4664
⇒ 22/7 × 28 × l = 4664
⇒ l = 53 cm
∴ Slant height i.e. l is 53 cm.
