Question

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

​

Answer 1

Answer:

$csa \: of \: cylinder \: = 2\pirh$

so the given height is = 10cm

and base = 7 cm

$by \: using \: formula$

$2 \times \frac{22}{7} \times 7 \times 10$

so the 7 is divided by seven and now 2×22× 10

= 44× 10 = 440

$your \: ans \: is \: = 440$

Answer 2

Answer:

110cm^2

Step-by-step explanation:

Given :

Height = 10 cm

Base = 7cm

Height = length

Base = diameter

Radius = d/2

= 7/2

= 3.5

Solution :

Curved surface of cone = pie r l

= 22/7 x 3.5 x 10

= 220 x 3.5 / 7

= 770/7

= 110 cm^2

One message, I edited my answer to mention this. Smartboy your answer is wrong because the question is circular cone not cylinder.
