Question

Plzzz solve question no.1 (ii). i'll mark you as a brainlist​

Answer 1

Answer:

231 cm

Step-by-step explanation:

The base of the cylinder is circular in shape.

Therefore area of base = pi*r*r

Therefore pi*r*r = 154 cm^2   (given)

(22/7)*r*r = 154

r*r = (154 * 7)/22

r*r = 7*7

Therefore radius of sphere = 7 cm

Given height = 1.5 cm

Volume of cylinder = pi * r * r * h  (formula)

Inserting values,

v = (22/7) * 7 * 7 *1.5

v = 231 cm

Hope u will get it friend!
