Question

The area of base of Right circular cylinder is 154cm² and its height is 15cm find the volumeof the cylinder

Answer 1

area of base of Right circular cylinder will be
= 154cm²
So,
154cm² = πr²
πr² = 154

Given that its height is 15cm
h = 15cm

Since, volume of cone = πr²h/3
But given that
πr² = 154 and h = 15
So,
volume of cone = 154 x ( 15 / 3 )
= 154 x 5
= 770

So, the volume of cone is 770
