Question

[|Cone|]

Find the curved surface area of a right circular cone whose slant height is 10 cm and Base is 7cm. ​
​

Answer 1

Answer:

220 cm²

Explanation:

Slant height of cone ( l ) = 10 cm

Base radius ( r) = 7 cm

CSA of cone = πrl sq.units

= 22/7 × 7 × 10

= 22 × 10

= 220 cm²

Therefore the curved surface area of cone is 220 cm².

Answer 2

$\huge \underline \mathfrak\pink {Question}$

Find the curved surface area of a right circular cone whose slant height is 10 cm and Base is 7cm.

$\huge \underline \mathfrak\pink {Answer}$

Given :-

• Height = 7cm

• Radius = 10 cm

Find:-

• The curved surface area of the cone

Solution :-

As we know ,curved surface area

= $\pi×radius ×length$

= $\frac {22}{7}× 7 × 10$

= 220 cm square

The answer is hence 220 cm square
