Find the curved surface area of a cone whose radius of base is 7 cm and slant height is 8 cm. [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 4
We know that,
Curved surface area = πrl
We have,
Radius of cone = r = 7 cm
Slant height of cone = l = 8 cm
Curved surface area of cone = \(\frac{22}{7}\) × 7 × 8 = 176 cm2
