Question

Find the volume of the cylinder given the area of its base is 154cm2 and height 8cm
​

Answer 1

Answer:

$\huge{\purple{\bf{\mathfrak{solution}}}}$

Height of cylinder = 8cm

area of base = πr²

154 = 22/7×r²

r²= 154×7/22

r²=49

r= ✓49= 7cm

Therefore,

Volume of cylinder = πr²h = 22/7×7×7×8

= 22×7×8 = 154×8 = 1232cm³..
