Question

the area of cone is 7cm and it's slant height is 10cm .find the CSA of cone​

Answer 1

Answer:

Curved surface area of cone is 220 cm².

Step-by-step explanation:

Question :-

• The base radius of a cone is 7 cm and its slant height is 10 cm. Find the curved surface area of the cone.

Given :-

• Base radius (r) = 7 cm
• Height (h) = 10 cm

To find :-

Curved surface area of cone.

Solution :-

C.S.A of cone = ${\pi}rl$

Where :

• $r$ - radius

• $l$ - slant height

Substituting :

• $\frac{22}{7}\times7\times10$

• $22\times10$

• $220$

∴ Curved surface area of cone is 220 cm².
