Question

7. The curved surface area of a right circular cone of helght 16 cm and base radius 12 cm Is
(a) 753.6 cm2 (b) 1205.76 cm² (c) 863.8 cm2 (d) 907.6 cm2​

Answer 1

Answer:

( b) 1205.76cm² ( Hope it helps you mate!)

Answer 2

question is misprint it is cylinder not cone

giving for both

for cylinder option (b)

The formula of curved surface area of a right circular cylinder =2 π×r×l

so putting the values = 2* 22/7 * 16 * 12 = 1205.76 cm2

for cone

The formula of curved surface area of a right circular cylinder = π×r×l

so putting the values = 22/7 * 16 * 12 = 602.88 cm2

hope u got it!
