Question

Csa of a cone is 550 a`nd its ba`se area` is 154. Find its volume

Answer 1

Answer:

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 * 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
