area of its base = 154cm²
22/7 × radius² = 154cm²
radius²=49
radius of the cone = 7
curved surface area of the cone = 22/7 * 7 * slant height
550 = 22/7 * 7 * l
550/22 = l
l=25 cm
l² = h² + r²
625 = h² + 49
h² = 576
h= 24
vol of the cone =1/3 *  22/7 * r² * h
22/7 * r² = 154
⇒1/3 * 154 * 24
volume of the cone = 1232cm³

Answer:

volume of the cone = 1232cm³

Step-by-step explanation:

area of its base = 154cm²

22/7 × radius² = 154cm²

radius²=49

radius of the cone = 7

curved surface area of the cone = 22/7 * 7 * slant height

550 = 22/7 * 7 * l

550/22 = l

l=25 cm

l² = h² + r²

625 = h² + 49

h² = 576

h= 24

vol of the cone =1/3 *  22/7 * r² * h

22/7 * r² = 154

⇒1/3 * 154 * 24
