Question

find the curved surface area of right circular cone whose slant
height is 10cm base diameter is 7cm​

Answer 1

Answer:

110cm^2

Step-by-step explanation:

l=10cm

d=7cm

r=3.5cm

C. S. A of a right circular cone = 22/7 x 3.5x 10

=110cm^2

Answer 2

Given:

• Slant Height = l = 10 cm
• Base diameter = 7 cm

So, Radius = 7/2 cm

To find:

• Curved surface area of cone = ?

Solution:

CSA of cone = πrl

⇒ CSA of cone = (22 × 7 × 10) ÷ (7 × 2)

⇒ CSA of cone = 110 cm²

∴ Curved Surface Area of right circular cone = 110 cm²

KNOW MORE:

• CSA or Curved Surface Area of a 3 dimensional shape is the area occupied by that object excluding top and bottom parts
• TSA or Total Surface area of a 3 dimensional shape is the area occupied by that object including top and bottom parts.
• TSA of come 2πr (r + l)
• Volume is the quantity of matter that can be fitted in an object.
