The radius of the base of a cylinder is 14 cm and its volume is 6160 cm3. The curved surface area (in cm2) is: $$\left( {\pi = \frac{{22}}{7}} \right)$$
Answer & Solution
Correct Answer:
Option
A
r = 14 cm
πr2h = 6160 cm3
Curved surface area = ?
$$\frac{{22}}{7}$$ × 14 × 14 × h = 6160
h = 10
Curved surface area = 2πrh
= 2 × $$\frac{{22}}{7}$$ × 14 × 10
= 880 cm2
πr2h = 6160 cm3
Curved surface area = ?
$$\frac{{22}}{7}$$ × 14 × 14 × h = 6160
h = 10
Curved surface area = 2πrh
= 2 × $$\frac{{22}}{7}$$ × 14 × 10
= 880 cm2
