Question

A right circular cone is 84 cm hight. The radius of the base is 350 m. Then the curved surface area is
A)385000 cm^2
B)358000 cm^2
C)835000 cm^2
D)345000 cm^2​​

Answer 1

Answer:

Step-by-step explanation:

Given:

h=8 cm

r=6 cm

Curved surface area =πrl

l= √h^2 + r^2

= √8^2 + 6^2

= √64+36

= √100  

=10 cm

∴ Curved surface area =3.14×10×10=314 cm
