Question

Diameter of right circular cone is 14m and its slant height is 10m. find curved surface area

Answer 1

Answer:

Step-by-step explanation:Diameter of right circular cone =14m

Radius of right circular cone = (14/2)m

Slant height of right circular cone = 10m

Curved surface area of right circular cone = 1/2×l×2πr=πrl

= (1/2×10×2×22/7×14/2)m²

= (10×11×7)m²

= 770m²

Therefore, the curved surface area of cone is 770m².

Answer 2

Given: Diameter=14 radius,r=7m
slant height,l=10m
To find=CSA
CSA of cone = πrl
=22/7×7×10
=22×10
=220m^2
