The curved surface area of a hemisphere with radius 7 cm is: (Take π = $\frac{22}{7}$) |
616 cm2 385 cm2 462 cm2 308 cm2 |
308 cm2 |
We know that, Curved surface area of hemisphere = 2πr2 We have, Radius of hemisphere r = 7 cm Curved surface area of hemisphere = 2 × \(\frac{22}{7}\) × 7× 7 = 308 cm2 |
