The curved surface area of a right circular cone is 44 cm2. If the slant height of the cone is 7 cm, then find the radius of its base. [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 1
We know that,
Curved surface area = πrl
We have,
Slant height of cone(l) = 7 cm
Curved surface area of a right circular cone = 44.
According to the question,
The curved surface area of the cone = πrl = 44 = 22/7 × 7 × r
= r = 2
