Answer 1

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

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.

Answer 2

$\huge\underline\mathrm{SOLUTION:-}$

AnswEr:

• The curved surface area of a right circular cone = 220 Cm².

Given:

• Slant height of a right circular cone is 10 Cm.
• Radius of a right circular cone is 7 Cm.

Need To Find:

• The curved surface area of a right circular cone = ?

ExPlanation:

According to the given question:

• Radius of the cone = 7 Cm
• Slant height = 10 Cm

Formula used here:

• Curved surface area of cone = πrl

Putting the values according to the given formula:

➠ $\mathsf {C.S.A = \frac{22}{7} \times 7 \times 10\:Cm^2}$

➠ $\mathsf {C.S.A = 22 \times 10\:Cm^2}$

➠ ${\underline{\boxed{\sf{C.S.A = 220\:Cm^2}}}}$

Hence:

• The curved surface area of a right circular cone is 220 Cm².

Additional Information:

HeRe,

• R is used for Radius.
• L is used for Length.
• C.S.A is used for Curved surface area.

• Curved surface area of cone = πrl
