Question

The radius of a cone is 7cms and its slant is 10cms find C.S.A.

Answer 1

C S A = 22/7 × 7 × 10

= 22/7 × 70

=22 × 10

= 220 sq.cm

therefore C S A of cone is 220sq.cm

Answer 2

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

AnswEr:

• The curved surface area of the cone = 220 Cm².

Given:

• The radius of a cone is 7 Cm
• Slant height of the cone is 10 Cm

Need To Find:

• Curved surface area of the cone (C.S.A) = ?

ExPlanation:

Formula used here:

• Curved surface area of cone = πrl

Putting the values according to the given formula:

➠ $\mathsf {\frac{22}{7} \times 7 \times 10}$

➠ 22 × 10

➠ 220 Cm²

• Hence, the curved surface area of the cone is 220 Cm².
