Question

# The slant height of an ice cream cone is 12 cm and its curved surface area is 113.04 sq cm. What is the radius of the base of this cone? (π = 3.14)

Solution

## Radius of cone (r) =? Slant height of cone (l) =12 cm Curved surface area of cone = 113.04 sq cm Curved surface area of a cone = πrl ⇒ 113.04 = 3.14 × 12 × r $⇒r=\frac{113.04}{3.14×12}$ ⇒ r = 3 cmMathematicsMathematics(2013)Standard VIII
